Paroxysmal auricular tachycardia due to reciprocal rhythm

摘要: A case of arrhythmia is analyzed and discussed in detail, evidence offered to indicate that the following were factors producing arrhythmia: 1. 1. Blocked Auricular Extrasystoles.—Re-entry into auricle from a ventricular by-pass; re-entrant waves not transmitted back again ventricles. 2. 2. Conducted auricles ventricles, i.e., reciprocal rhythm. 3. 3. Attacks Paroxysmal Tachycardia.—A continuously circulating wave excitation between ventricles auricles, rhythm perpetuated over some length time.
