WebSinus arrhythmia is a kind of arrhythmia (abnormal heart rhythm). For the most common type of sinus arrhythmia, the time between heartbeats can be slightly shorter or longer depending on whether you’re breathing in or out. Your heart rate increases when you breathe in and slows down when you breathe out. This kind of arrhythmia is considered ... WebR-wave amplitude in leads I, II and III should all be ≤ 20 mm. If R-wave in V1 is larger than S-wave in V1, the R-wave should be <5 mm. (1 mm corresponds to 0.1 mV on standard ECG grid). R-wave peak time.
