The correct diagnosis is sinus bradycardia with a sinus pause due to sinus node arrest (Figure 2). Figure 2. Courtesy of Philip J. Podrid, MD. The rhythm is regular except for one long RR interval or ...

Sinus bradycardia, or a slow heart rate, can be a sign of cardiovascular health in healthy young adults and endurance athletes. It can also be a sign of an underlying condition requiring medical ...

The correct diagnosis is sinus bradycardia, AV dissociation, and accelerated junctional rhythm and occasional capture (Figure 2). The other QRS complexes occur at a regular interval and a rate of 42 ...

Sports cardiology has emerged as a distinct subspecialty at the intersection of preventive cardiology and athlete care. While ...

Sinus arrhythmia is when your heart beats too slowly or too fast. The change of pace may happen when you breathe. This condition is common and usually benign. But, it could indicate an underlying ...

Learning the art of ECG interpretation requires intellect, commitment, effort and — perhaps most importantly — an organized approach. I have spent thousands of hours (yes, thousands) looking at ...

Tachycardia and bradycardia are two types of irregular heart rates. Tachycardia is when the heart beats faster than 100 beats per minute. Bradycardia is when the heart beats slower than 60 beats per ...

A 76-year-old man presented to the emergency department with lethargy and a reduced level of awareness after a period of experiencing a very low heart rate. The patient said he did not feel faint or ...

Sinus bradycardia occurs on an ECG when there is a normal upright P wave in lead II (sinus P wave) preceding every QRS complex with a ventricular rate of less than 60 beats per minute. Frequently, ...
