The ECG criteria to diagnose sinus arrhythmia is a variation of the P-P interval, from one beat to the next, of at least 0.12 seconds, or 120 milliseconds. Sinus arrhythmia ― if not in a young ...

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, ...

There are only a few sinus rhythm QRS complexes available to examine on this ECG. Using lead V1 an incomplete right bundle branch block is seen. A prolonged QT interval is present that extends all ...

ECG interpretation in athletes requires careful analysis to properly distinguish ... early repolarisation, sinus bradycardia, sinus arrhythmia and 1° atrioventricular block. Abnormal findings are ...

Sinus arrhythmia is a variation in the heart's sinus rhythm, usually caused by changes in a person's breathing cycle. It's a ...

Electrocardiography demonstrated a slowing of the sinus rhythm followed by a single PVC (of the same QRS morphology described above), inducing polymorphic VT that degenerated into ventricular ...

Routine ECG recorded through noninvasive, cheap and easily available tolls have markers that portend higher stroke risk. Atrial fibrillation (AF) is the most common clinical arrhythmia ...

We excluded the dog from surgery due to its abnormal ECG and the increased risk of potentially lethal arrhythmias during ... right auricular appendage, sinus node, left auricular appendage ...

Mice exhibit a well-documented circadian rhythm and ECG parameters comparable to humans ... With a sustained block of the SNS, the researchers observed loss of the day-night rhythm in sinus node ...
