Brief Summary
The investigators have previously shown that a frequency of 15.95-16.00 Hz protects against acute myocardial infarction in rats. In the current study the investigators would like to investigate whether this frequency enables cardiac patients with exercise-induced chest pain to exercise at higher workload and heart rate. Therefore, patients will undergo two exercise stress tests, one test after being exposed to 30 minutes of the above mentioned frequency and another test after being exposed to sham (no frequency is turned ON). The investigators will measure changes in the electrocardiogram (ECG), workload, exercise time, and subjective measure of chest pain (angina).
