Cardiac Stimulation

Sedating cardiac stimulation (SERCA stimulation, from the English SERCA - SERially activating Ca²+ ATPase) is a method of stimulating the heart with sequentially activated action potentials (PDS), which allows you to increase the endurance of the heart muscle by increasing the concentration of Ca2+.

The PDS stimulation method was first described in a study of patients with coronary artery disease suffering from chronic systolic heart failure. During this study, it was found that when the heart was stimulated with pulses, each subsequent pulse, appearing at certain intervals, had a stronger stimulating effect on the heart muscle compared to the first pulse. This phenomenon is called saddled cardiac pacing.

Scientific explanations for the effect of sedentary stimulation are associated with an increase in calcium concentration in the smooth muscle cells of the heart muscle and its depolarization. Moreover, this technique can speed up your heart rate for a short time and reduce the risk of gastric fibrillation.
