A simple procedure for positioning precordial ECG and VCG electrodes using an electrode locator.

Methodological differences in the placement of precordial ECG electrodes are a major problem in multicenter clinical trials and epidemiological studies. Trend analysis and realization of the full potential of computer programs for serial comparison demands reduction of technical sources of variation in the electrocardiogram (ECG) and vectorcardiogram (VCG) and particularly errors in locating ECG electrodes. The ECG electrodes locator described here reduces a major precordial uncertainty in the identification of the midclavicular and the anterior axillary lines. It simplifies positioning and provides a numeric record of the key precordial electrode positions, facilitating control of electrode placement errors in serial recordings.

Epidemiology and prevention of ventricular ectopic rhythms.

Current work of the Laboratory of Physiological Hygiene is reviewed on the epidemiology and prevention of ectopic ventricular rhythms (VPB). The evidence suggests that uniform simple VPB at rest, or exercise-induced, are prognostically important only in those having clinically manifest coronary disease. A simple rhythm strip is an effective first screen method for detecting individuals having rather frequent VPB, and frequency of VPB is correlated with complex ectopic rhythms. A multifaceted stress induction test induces VPB and does it consistently. Hygienic intervention, in which cardiac stimulants are removed and conditioning exercises given, is being tested as VPB suppressive therapy.
