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.

In fact, up to 60% of athletes demonstrate ECG changes (in isolation or in combination) such as sinus bradycardia, sinus arrhythmia, first-degree atrioventricular (AV) block, early repolarisation, ...

High vagal tone in athletes results in bradycardia and repolarization anomalies on the resting ECG. Bradycardia permits enhanced diastolic filling, which in turn results in highly effective ...

ECG interpretation in athletes requires careful analysis to ... meeting voltage criteria for left ventricular hypertrophy, early repolarisation, sinus bradycardia, sinus arrhythmia and 1° ...

The most common ECG finding of an acute pulmonary embolism ... contractions occurring in a pattern of bigeminy can mimic sinus bradycardia. Coarse “fibrillatory waves” can be seen during ...

and 8% had sinus bradycardia. Preoperative ECG was normal in 18% of the PPM patients. Overall, 4,678 (75%) patients underwent isolated CABG. The distribution of PPM patients in relation to the ...
