Nonetheless, if a person suspects anomalies in the rhythm of their heart rate, they should contact a doctor for a diagnosis. In sinus tachycardia, the heart rate increases but continues to beat ...

More patients in the PM group were on AADs (PM 40.4%, ABL 4.7%, P < 0.001) while sinus rhythm maintenance was remarkably higher in the ABL group at the end of follow-up (83.7% vs 21.1% in PM group ...

Amiodarone effectively maintains sinus rhythm in patients with atrial fibrillation, and although dronedarone is less effective it has a better safety profile. The choice of antiarrhythmic drug (or ...

Among the 85 such cases identified, 16 were excluded from the study because the atrial fibrillation or flutter spontaneously converted to sinus rhythm, warfarin therapy was not administered before ...

Although prolonged auscultation alone would have been sufficient to determine the presence of an arrhythmia (above and beyond the sinus arrhythmia) and would suffice in a clinical setting ...

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, ...
