In tracing "a" of Figure 1, there seems to be only one P wave in front of each QRS complex, suggesting sinus rhythm. However, during the compensatory pauses after the PVCs (↑) in tracing "b," there ...

This is a challenging ECG in regards to determining if the wide QRS complex rhythm is from ventricular tachycardia or "SVT with aberrancy" such as AV nodal reentry tachycardia causing a rate-dependent ...

This ECG is challenging. The rhythm starts as normal sinus rhythm with a right bundle branch block, then a wide-complex tachycardia develops in a left bundle branch block pattern. The important thing ...

Losartan, enalapril and amlodipine reduced the number of premature ventricular contractions (PVCs) in patients with essential hypertension as well as blood pressure. The effect of losartan was the ...

Dr. James Daubert answers the question: 'Finding Cause Of Palpitations With EKG? — -- Question: How does an EKG (electrocardiogram) help in finding out why I have palpitations? Answer :Well, an ...

A narrow QRS tachycardia at a rate of 105 beats/min. is present. No P waves are identified in front of the QRS complexes, suggesting accelerated AV junctional rhythm. However, there are two PVCs.
