Sinus node dysfunction occurs occasionally after heart transplantation and may be caused by surgical trauma, ischemia to the sinus node, rejection, drug therapy, and increasing donor age. However, the timing and indication of permanent pacemaker insertion due to sinus node dysfunction following heart transplantation is contentious. Here, we report a case of a permanent pacemaker insertion for s...

Dysautonomia in Guillain-Barre syndrome (GBS) rarely causes serious cardiovascular complications, such as sinus arrest. Miller Fisher syndrome (MFS) is recognized as a variant of GBS. There have been few reports regarding the association between MFS and dysautonomia. We describe a case of a 68-year-old man with ophthalmoplegia, bulbar palsy, truncal ataxia, and areflexia. He was diagnosed with ...

The results are given of a 4-year prospective study regarding the occurrence, clinical pattern, and treatment of sinus arrest in patients with acute myocardial infarction. The arrhythmia was observed in 32 of 1665 patients. The detection rate increased from below 1 per cent in the first year to 5 per cent in the last due to better facilities for monitoring. All patients except one had inferior ...

We are reporting an extremely prolonged sinus arrest documented by Holter monitoring.

An obese man, with an attack of myocardial ischaemia, developed arrhythmias only when he was asleep. Episodes of sinus bradycardia occurred progressing to arterioventricular block and sinus arrest. These changes in the cardiac rhythm coincided with periods of sleep apnoea.

In human several kinds of electrocardiographic findings have been reported in association with pneumothorax such as decreased and/or alternating QRS amplitude (electrical alternans). However, electrocardiographic changes concurrent with pneumothorax have rarely been discussed in veterinary literature. A 3-year-old male crossbreed dog was presented with a history of car accident. Thoracic au...

course. All ages are affected and the diagnosis must be considered if there is a modest degree of sinus bradyeardia (SB), even if asymptomatic, as SB is less benign than was heretofore thought. Inappropriate or relatively slow sinus rates (RSSR) under stressful conditions are equally as important as SB. Inadequacy of the sinoatrial node (SAN) may be manifested by one or more of the following: (...
