How do the digitalis?
Digitalis make the heart beat stronger by increasing the amount of calcium in heart cells. (Calcium stimulates the heartbeat.) When the drug reaches the heart muscle, binds to receptors sodium and potassium. These receptors control the amount of calcium in the cardiac muscle calcium stopping the output of the cells. As calcium builds up in the cells, increases the strength of the heartbeat.
Digitalis controls the heart rhythm irregularities (called arrhythmias) by slowing the signals that originate in the sinoatrial (SA). This in turn reduces the number of signals passing through the atrioventricular (AV). A small number of signals involve a small number of arrhythmias.
