GRAPHIC TECHNIQUES IN CARDIOLOGY
Resistant Ventricular Tachycardias and Recurrent Cardiac Arrests: 96 Episodes

https://doi.org/10.1378/chest.71.3.426Get rights and content

A 66-year-old man suffered an acute myocardial infarction complicated by multiple episodes of ventricular tachycardia and 96 episodes of ventricular fibrillation requiring cardioversion over a period of 55 days. Following ventricular aneurysmectomy, the ventricular tachycardia persisted. This converted to regular sinus rhythm with a regimen of disopyramide phosphate, quinidine, and propranolol.

Case Report

A 66-year-old man with chest pain was admitted to the Swedish-American Hospital on Aug 18, 1973. The initial electrocardiogram and findings from enzymatic studies were normal. On the third day of hospitalization, classic myocardial infarction was confirmed by the ECG and cardiac enzymatic studies. On the next day the patient developed atrial fibrillation requiring administration of digoxin. His course was stable until the 20th day of hospitalization, when he developed severe chest pain and lost

Discussion

As seen in this case, ventricular tachycardia refractory to all known treatment programs remains a challenge requiring therapy individualized to the particular patient. With this patient a multiple drug regimen monitored with determinations of serum drug levels was instituted to no avail. Rapid cardiac pacing2-4 was not beneficial prior to and after ventricular aneurysmectomy. The surgical approach to life-threatening ventricular tachycardia with aneurysmectomy and coronary arterial bypass
