Abstract

The detection and correction of ventricular fibrillation at the earliest time after its onset is essential to ensure long-term survival. During successive cardiac arrests the rhythms occurring were sensed by using disposable pre-gelled ECG defibrillator pads placed in the anterior-anterior position. Simultaneously with the treatment, the arrest rhythms were analyzed continually every 8 to 18 seconds by a microprocessor system. This system sampled digitally the electrocardiogram, and the algorithm looked for absence of the isoelectric segment, irregular energy density spectrum, and irregular wave shape. The analysis was displayed visually as ventricular fibrillation (VF) or non-VF, and simultaneously the ECG and system's analysis were recorded on tape. Later, the system's interpretation of the rhythm was compared with the ECG record. There were 46 males and 32 females. Their ages ranged from 14 to 85 years, with a mean of 63 years. Twenty-nine patients had sustained an acute myocardial infarction. In the remaining 49 patients, there were a variety of causes for cardiac arrest, including heart failure, vasovagal syncope, cardiomyopathy, and postoperative cases. We report in detail the process and results.
