Research into the application of electrocardiography in buffaloes has been lacking when compared to other species. However, identification of altered health states, whether for identification of healthy animals or for the measurement of treatment effects is vital for research. Several electrocardiogram (ECG) changes were shown to occur in buffaloes naturally infected with Theileria annulata inc...

A case of sick sinus syndrome, which was originally diagnosed during 1958, had an extensive followup for over 20 years by several clinicians. He showed a wide spectrum of associated rhythm disorders includ-tng sinus irregularity, extrasystoles, paroxysmal supraventricular tachycardia and Wenkebach's phenomenon. He remained physically fit and active, and did not require active medications, and d...

A 66-year-old woman with a 24-year history of paroxysmal supraventricular tachycardia underwent an electrophysiologic procedure. The baseline sinus cycle length, atrial-His (AH), and Hisventricular (HV) intervals were 8(X). 70, and 40 msec, respectively. Programmed stimulation with a single atrial extrastimulus did not demonstrate dual AV nodal physiology and did not result in the induction of ...

Catheter ablation of ventricular tachycardia (VT) currently has an important role in the treatment of incessant ventricular tachycardia and reduction of the number of episodes of recurrent ventricular tachycardia. Conventional mapping techniques require ongoing tachycardia and haemodynamic stability during the procedure. However, in many patients with scar-related ventricular tachycardia, non-i...

Plasma atrial natriuretic peptide was measured in 13 children between the ages of 1 week and 2 years 9 months during atrioventricular re-entrant tachycardia and 15 minutes after the restoration of sinus rhythm. There was a significant decline in atrial natriuretic peptide during sinus rhythm. Plasma concentrations of the peptide were significantly higher during tachycardia in seven infants unde...
