Stretch-induced modifications of myocardial performance: from ventricular function to cellular and molecular mechanisms.

abstract：:Twenty patients who had suffered myocardial infarction within the previous 3 to 13 days performed face immersion with breath-holding. The maximum reduction in heart rate was 17 +/- 9 beats-min--1 (mean +/- SD). When compared with 24 patients without evidence ischaemic heart disease, they behaved more like younger pati...
