Diagnostic Methods Arrhythmiia
Differentiation of wide QRS complex tachycardias on surface electrocardiograms is difficult for physicians and computers due in part to their inability to identify atrial activity, specifically atrioventricular (AV) dissociation. We studied 20 examples ofAV associated rhythms and 17 examples ofAV dissociated ventricular tachycardia. We applied an algorithm consisting of subtraction of a mean be...
متن کاملMechanism of synchronization in isorhythmic A-V dissociation. 3. Computer model.
An analog computer model has been developed to study the mechanism of the atrioventricular synchronization in one type of isorhythmic A-V dissociation (pattern I). The computer model simulates the following biological feedback control system: (1) the ventricular pacemaker frequency is independent of arterial blood pressure (analogous to artificial ventricular pacing); (2) the frequency of the a...

متن کاملSustained Supraventricular Tachycardias Following Open Heart Surgery
A technique is described to control recurrent or sustained supraventricular tachycardia associated with rapid ventricular rates following open heart surgery. The technique utilizes a pair of temporarily implanted atrial epicardial wire electrodes to pace the heart. In one group of patients with recurrent atrial flutter and 2:1 A-V conduction, continuous rapid atrial pacing at 450 beats/min prod...
متن کاملAnswer to the Rhythm Puzzle
The ECG (electrocardiography) shows a sinus bradycardia of 42 beats/min, a horizontal electrical heart axis and a narrow QRS complex. The second to fourth QRS complex is preceded by a P wave with a variation in the PQ time. The PQ time in the second QRS complex is 220 ms, in the third 200 ms and the fourth 140 ms. No P wave precedes the fifth QRS complex. In the sixth QRS complex, the P wave is...
