For many nursing students and new nurses EKG interpretation can be intimidating, to say the least. I remember my first day as a nurse in the ICU. To say that I was overwhelmed is a pretty big understatement. In fact you can interpret ANY heart rhythm in just 5 simple steps. Following the steps below will allow ease with interpretation of arrhythmias.
Typically, the physician will ask about the latest labs, intake and output, vitals, as well as which medications the patient received so far today. Cardiac rhythm strip exercises provide interactive learning reinforcement. Afib also causes the heart to undergo a process called remodeling where the walls thicken Heart rythem strips the heart ryhhem increases. The PR interval is normal or prolonged. Whenever ordered by the physician, you would then initiate Coumadin and monitor this with the INR. If the blood clot breaks free it can cause a stroke or pulmonary embolism PE and increased the risk of heart failure and death. What causes Sinus Tachycardia? Second degree type 2 Mobitzhowever, is caused by damage to the bundle branch system following an acute Hearf Myocardial infarction. The QRS complex will typically Heart rythem strips 0.

T wave is normally a smaller than QRS upwards waveform, indicating ventricular repolarization. VFib can be caused by: acute myocardial infarction trauma drug overdose such as heroin electrolyte imbalances Ventricular tachycardia will become Heart rythem strips fibrillation if it is left untreated. Pulseless Rhythms. Essential ECG features are explained along with step-by-step analysis techniques. This includes rhythm evaluation, determining heart rate and assessing multiple components of the EKG waveform. Medications can be used to control a patients rate and rhythm. This is done because patients cannot take heparin at home in the dose that is required for this purpose. During rytehm single heart beat, several electrical events occur. T wave is normally a smaller than QRS upwards waveform, indicating Hert repolarization. Share this post:. The Heart rythem strips beat very fast, irregularly and out of sync How mwn masturbate the ventricles. Cardiac Rhythm Strips Guide. You will need to get the crash carts and place the pads on the patients and shock them.
It is a quick and painless procedure.
- A synopsis of the cardiac rhythm dysrhythmia is provided and electronic calipers can be used to study each tracing.
- These pages cover all of the cardiac arrhythmias that you will experience in the ACLS provider course.
- Our cardiac rhythm strips guide provides information on essential dysrhythmia categories:.
- The quick identification of life-threatening rhythms in the critical care setting and in the ACLS certification setting usually does not involve looking directly at ACLS rhythm strips on paper, but rather it involves looking at a defibrillator or ECG monitor and rapidly evaluating a rhythm based upon what is seen on the monitor.
It is a quick and painless procedure. EKGs captures a tracing of cardiac electrical impulse as it moves from the atrium to the ventricles. These electrical impulses cause the heart to contract and pump blood. EKGs are interpreted by medical professionals to understand the following:. This introductory course reviews the main features of electrocardiogram strips. A method for analyzing an electrocardiogram is presented.
This method includes assessment of rhythm, calculating heart rate, observing P-wave forms, measurement of wave intervals and segments and the evaluation of other relevant waves. In addition, our drills allow students to practice electrocardiogram identification. Immediate feedback is available after answering a multiple choice question. Our quiz presents twenty tracings for interpretation.
A graded quiz provides detailed feedback. Quiz ekg tracings are randomly selected from our database of tracing, so the quiz can be repeated many times. For each type there are patient tracings and simulated electrocardiograms. We also provide an annotated tracing with a summary of the key features and values. Interactive digital calipers can be used for measuring key features on each tracing.
Our Monitor Quiz is similar to the standard Quiz, but with a twist. Instead of static tracings, the ECGs are presented using a simulated patient monitor. After the twenty tracings are evaluated, we present a graded report along with static images of each tracing. Your score is compared to a mean score for all recent website visitors. Don't worry, your score is kept private.
The EKG rhythm will appear regular. The heart rate is bpm, which is faster than a ventricular rhythm but slower than ventricular tachycardia. The P wave is absent and PR interval is not measurable.

For many nursing students and new nurses EKG interpretation can be intimidating, to say the least. I remember my first day as a nurse in the ICU. To say that I was overwhelmed is a pretty big understatement. In fact you can interpret ANY heart rhythm in just 5 simple steps. Following the steps below will allow ease with interpretation of arrhythmias. Analyzing strips in this order and reviewing these 5 aspects will allow for correct identification of cardiac rhythms.
Before we move forward and explain this any further let me give you a handout that includes 10 common EKG rhythms with strips. Normal Sinus Rhythm. Normal sinus rhythm is the result of the electrical conduction following the intended course without deviation or alteration in rate.
Slight variations in rhythm regularity may be noted with the respiratory cycle. This is the BEST place to start. But this is just the beginning. In order to become an EKG master you need to become comfortable with a wide range of rhythms.
Lets dive into how to interpret different rhythms. Bradycardia, or sometimes called Brady, is defined as a heart rate under 60 beats per minute BPM. However, when you count out the heart rate it is less than 60 bpm.
Other common causes of sinus brady include:. Patients with sinus bradycardia will likely be asymptomatic, however, it makes sense for patients to exhibit signs and symptoms of cardiac compromise such as:. Transcutaneous pacing should be used if the patient is exhibiting signs and symptoms of poor profusion. AV Blocks. There are three degrees of AV block, in the second degree, there are two types. I personally have found these to be very confusing and still to this day, I do not recognize these heart blocks at first glance, I have to slow down and take my time reading the EKG strip to get the right type of block.
First degree AV block, second degree type 1 AV block, and third degree AV block can be caused by the following issues:. Second degree type 2 Mobitz , however, is caused by damage to the bundle branch system following an acute anterior Myocardial infarction. It is important to note that second degree type 2 AV block is NOT caused by medications or increased vagal tone.
The main goal of treating AV block usually depends on if the patient is symptomatic or not. If they are not symptomatic and their heart rate is sustaining appropriate profusion, then the goal is to monitor PR intervals and make sure that the heart block conduction system does not worsen.
In each specific degree of heart block, you will want to follow the following:. Sinus Tachycardia. All wave forms are present on the EKG making this a fast but steady arrhythmia. Sinus Tachycardia causes decreased cardiac output due to inadequate ventricular filling as well as an increased oxygen demand for the myocardial cells. A patient with sinus tachycardia may have the following signs and symptoms:. The best treatment for sinus tachycardia is to treat the underlying cause.
If a patient has a fever, administer antipyretics such as Motrin or Tylenol , or if they have anxiety give them an antianxiety medication such as Xanax , Valium or Ativan. If the patient has a narrow QRS complex, then treat them with the following:.
If the patient has a wide QRS complex, then treat them with an antiarrhythmic such as Procainamide , Amiodarone , or Sotalol. When the sinoatrial SA node is not generating proper electrical activity, the hearts atrial tissues or even other tissues of the heart will attempt to generate electrical action potential.
This can cause issues with the heart not beating properly, completely, or rhythmically. Watch this video below:. It is an umbrella term to cover multiple types of tachycardia, however, people often will refer to paroxysmal supraventricular tachycardia PSVT as SVT. The heartbeats can be inconsistent or consistent and are always fast. It is called paroxysmal because it happened intermittently and lasts various lengths of time. However, certain behaviors such as alcoholism, caffeine, drug use, or smoking can put you at risk as well.
Patients who have sustained PSVT can have adverse effects such as hypotension due to the inevitable incomplete heartbeats from the fast beating of the heart. As well as over time, the heart will enlarge Cardiomegaly and eventually fail heart failure. Because PSVT can be treated by the patient by themselves, the first line of treatment involves performing the Valsalva maneuver where the patient holds their breath and bear down as if they were having a bowel movement, or cold water on the face splashing or submerging.
Coughing while positioned sitting forward can also bring someone out of PSVT. In the hospital, a patient may get a carotid massage by a physician, medications such as adenosine Adenocard and cardioversion. The atria beat very fast, irregularly and out of sync with the ventricles. The atria are often getting such confusing signals that they will quiver. No discernible P waves. The ventricular rate is often bpm and the QRS complexes is usually less than ms.
The actual cause of Afib is unknown but research suggests many risk factors that are commonly seen with patients with Afib.
Due to the pooling of blood from incomplete contractions and the quivering of the atria, a patient is likely to form a clot. If the blood clot breaks free it can cause a stroke or pulmonary embolism PE and increased the risk of heart failure and death. Afib also causes the heart to undergo a process called remodeling where the walls thicken and the heart size increases.
Medications can be used to control a patients rate and rhythm. Cardizem is better at controlling the rhythm but can cause hypotension in the patient, whereas amiodarone is better for hemodynamically compromised patients. Anticoagulants are used for stroke and pulmonary emboli prevention.
Heparin is the first line, however Lovenox and warfarin Coumadin are also used. If medication has not been successful in controlling rate or rhythm, the patient may have a medical procedure to correct this arrhythmia.
Atrial Flutter AFlutter. Atrial Flutter , commonly called Aflutter or AFL, is very similar to Afib except that the heart still is beating at a regular rhythm. The Sinoatrial Node SA node sends electrical impulses through the atria at a very fast rate, sometime the electrical impulse is so fast it circulates around the atria.
The Atrioventricular Node AV Node receives this electrical impulse and with the combination of slowing down the rate as well as the intrinsic beat for the AV Node bpm , the ventricles still beat at a regular rate and rhythm. This was always the easiest rhythm for me to pick out because it is so unique.
The jagged edges are similar to that of a saw blade, and people refer to it as a saw tooth pattern. The rate is regular, but fast. Ventricular Rhythms. These are located in the ventricles. This is the end of the road for pacing the heart and the body cannot sustain life using the ventricles only for very long. Ventricular Tachycardia Vtach Ventricular Tachycardia VTach is a rapid heartbeat above bpm originating in the ventricles. This is one of the shockable rhythms, the other is Ventricular Fibrillation.
The rhythm is regular but the rate is fast above bpm. The QRS complex is widened and P waves can be difficult to identify. This is a very easy rhythm to glance at and interpret due to its characteristic waves. This is managed through medications such as Lidocaine, Procainamide , Sotalol, or Amiodarone , defibrillation and possible cardiopulmonary resuscitation CPR.
Ventricular Fibrillation VFib. Untreated Ventricular Tachycardia leads to VFib. The ventricles quiver because the electrical activity is disordered. This quivering causes the heart to not be able to pump blood, leading to cardiac arrest. VFib is easily recognized because of its rapid, chaotic, and irregular nature. The QRS complexes are variable in height and width as well as there are no P waves. Ventricular tachycardia will become ventricular fibrillation if it is left untreated.
Your patient will likely lose consciousness and they will not have a pulse. VFib needs to be recognized and treated immediately because it leads to cardiac arrest and death. With VFib, it is super important to defibrillate as soon as possible.
For further details about running a code, check out the ACLS algorithm. Whenever I first notice this, I typically get a full set of vitals. Electrolyte imbalances can cause an increase in PVCs, so I like to have all of this information before I call the physician. Typically, the physician will ask about the latest labs, intake and output, vitals, as well as which medications the patient received so far today.
If these imbalances and issues are treated early, you may avoid a coding patient later on in the shift. A very common complication from cardiac surgery is atrial fibrillation. This is a major, drop everything right now priority. You will need to call the physician STAT — however one of the first questions the physician is going to ask is what the blood pressure is.
Therefore, I highly recommend finding out what the blood pressure is and if the patient is symptomatic first. For example, delegate obtaining a full set of vitals to a nursing assistant while you quickly assessed the patient and call the physician.
The automatic blood pressure machines do not accurately read atrial fibrillation. Therefore, if your patient flips into a fib with RVR you must obtain a manual blood pressure.
