Abstract:
24-hour Holter ambulatory ECG monitoring has been examined for the cardiac evaluation during ordinary activities in 81 subjects with suspected or propostmyocardial infarction (PMI), 12-lead ECG and the 24-hour ECG tape showed similar basic rhythm, heart rates and conduction patterns, but ventricular premature contractions (VPCs) were more frequently recorded on the 24-hour tape. Of 17 PMI patients, one or more VPCs in 14 cases (82.4%), multifocal VPCs in 3 cases (17.6%) and bigeminy or paired VPCs in 5 cases (29.4%) and transient runs of ventricular tachycardia in 1 case (5.9%) were observed on the 24-hour monitoring. 2) Of 30 patients with typical or atypical chest pain, 20 examinees had changes in the ST segment and/or T wave, but 10 examinees did not have any pathological changes in the ST segment or in the T wave. 3) Of 26 patients with dizziness and palpitation during waking periods, sinus rates were 76.4+/-12.8/min. and the ranges were 134.1+/-15.1/min. and 58.7+/-9.1/min. Average sinus rates observed during sleeping periods were 61.6+/-10.3/min., the ranges were 92.7+/-11.4/min. and 51.5+/-8.7/min. In general, longer PR interval, QTc interval, QRS duration and high R amplitude were observed during sleeping periods than waking periods. 4) Of 64 patients without PMI, all subjects had episodes of normal sinus rhythm and brady-and-tachycardia syndrome in 5 cases, VPCs in 23 cases, APCs in 2 cases, AV block in 4 cases and W.P.W. syndrome in 2 cases were observed during 24-hour Holter ECG monitoring.
