“…Ten percent of the normal subjects had more than 10 ventricular ectopic beats•h -1 [22]. These findings in normal subjects were consistent with 21 other studies, also there were wide variations in these studies [22]. The modest increase in ventricular arrhythmias in our OSA patients lies between the increase found in studies of patients with severe OSA [1,2,4,7,8] and patients with less severe OSA [11].…”

“…In the OSA group, less patients showed Lown 0 as compared to the snorers, but there was no difference in the presence of simple or complex ventricular arrhythmias (table 3). In normal subjects at our institution, the incidence of Lown I+II was 41%, Lown III 17%, and Lown IV 7% [22], and was thus below the incidence found in the OSA patients (table 3). Ten percent of the normal subjects had more than 10 ventricular ectopic beats•h -1 [22].…”

Patients with obstructive sleep apnoea demonstrate an increased rate of ventricular arrhythmias. The present study was designed in order to investigate whether these arrhythmias may be related to myocardial injury, since myocardial injury of various aetiologies has been observed to change the signal averaged electrocardiogram (ECG). Signal averaged ECG was registered in 23 patients with obstructive sleep apnoea diagnosed by polysomnography (apnoea index 43 +/- 20 events.h-1, age 55 +/- 10 yrs). QRS duration, root mean square voltage of the last 40 ms of QRS, and low amplitude (< 40 mV) signal duration were determined from the vector magnitude of the QRS, high-pass filtered at 40 Hz. Patients with coronary heart disease or bundle branch block were excluded. No patient showed an abnormal signal averaged ECG. Mean duration of the filtered QRS complex was 96 +/- 9 ms, root mean square voltage 38 +/- 18 microV and low amplitude signal duration 26 +/- 8 ms. These results were not significantly different from 14 snoring subjects with an apnoea/hypopnoea index < 10. Four patients showed no ventricular arrhythmias and six patients had Lown III or IVa in the Holter ECG. Echocardiography revealed increased left atrial (43.7 +/- 4.1 mm) and interventricular septal diameters (11.3 +/- 1.4 mm). In conclusion, obstructive sleep apnoea does not generate a substrate for late potentials in the signal averaged ECG.
