Sinus bradycardia – sinus rhythm below 60 bpm is a sinus bradycardia. AFIB/AFL – atrial fibrillation or atrial flutter episodes. Sinus tachycardia – sinus rhythm above 100 bpm is a sinus tachycardia. In healthy individuals occurs during exercising or strong emotions.

The WCT is interrupted by a series of variable-morphology QRS complexes, with atrial flutter waves note in II, III, and aVF. Detail of Flutter waves The rate of the flutter waves matches the rate of the WCT (about 200/m), proving that the presenting WCT had been 1:1 atrial flutter.

REM Sleep: Each percent increase in nightly REM sleep duration was associated with a lower risk of atrial fibrillation, atrial flutter, and bradycardia (an abnormally slow heart rhythm). Deep sleep: Each percent increase in deep sleep was associated with a lower risk of atrial fibrillation, depression, and anxiety.

Instead, the rate of 150, plus the history of AF, suggested atrial flutter. A close inspection of lead II showed P or flutter waves at a rate of about 300 bpm, also supporting atrial flutter. There appear to be flutter waves at a rate of 300. Flecainide encourages new atrial flutter.

The August 17, 2020 post by me in Dr. Smith's ECG Blog — in which I review the phenomenon of Bradycardia-dependent BBB ( sometimes called "Phase 4" or "paradoxical" block ). ECG Blog #242 — Reviews rate -related BBB. ECG Blog #32 — More on rate-related BBB.

PVCs N ot generally considered abnormal ECG findings: Isolated PAC, First Degree AV Block, Sinus bradycardia at a rate of 35-45, and Nonspecific ST-T abnormalities (even if different from a previous ECG). Thus, if there is documented sinus bradycardia, and no suspicion of high grade AV block, at the time of the syncope, this is very useful.
