Angina induced by excessive bradycardia

Nodal bradycardia induced by tocainide.

A case of tocainide-induced nodal bradycardia in standard recommended dose is reported. There was no recurrence when the drug was subsequently reintroduced in a reduced dosage. It is suggested that in the elderly, tocainide should be used in a lower dosage than normally recommended.

Variant angina induced by biliary colic.

A 65 year old woman with gall stones presented with crushing chest pain after an attack of biliary colic. The electrocardiogram showed ST segment elevation in leads I, aVL, and V1-V3 while leads II, III, and aVF showed ST segment depression. Cardiac enzyme activity remained within the normal range. During the next three weeks attacks of epigastric and right hypochondrial pain preceded by crushi...

Low dose methylprednisolone induced bradycardia.

Methylprednisolone induced arrhythmias, especially bradycardia, are well known. Most of the available reports suggest the occurrence of these arrhythmias with high dose intravenous therapy. We, hereby report a case of low dose methylprednisolone induced bradycardia.

Hemodynamic accompaniments of angina: a comparison during angina induced by exercise and by atrial pacing.

The hemodynamic responses of nine patients with severe coronary artery disease were studied during the precipitation of angina by both supine exercise and increasing rates of atrial pacing. Tension-time index and the first derivative of left ventricular pressure pulse (LV dp/dt) at the onset of angina were significantly higher (P < 0.01) in each patient when angina was induced by exercise than ...
