Bradycardia can be because of lots of reasons. Most important reason is patients can have heart attack and have bradycardia. Bradycardia means low heart rate. Bradycardia can also be because of myocarditis, pericarditis, lots of other reasons like hypothyroidism, drugs like digoxin, beta blockers, which has been given for hypertension or anti arrhythmic drugs where the patient is having irregular heart rate. Even those drugs can cause bradycardia. Even if there is excess potassium in the blood you have to correct potassium. If there is heart attack, pericarditis, myocarditis, you have to treat those conditions. If there is excess of beta blockers and digoxin, you have to stop those medications. If there is intractable bradycardia, we have to put the patient on permanent pacemakers, that is the lead is passed on the femoral vein and hooked into the right ventricle and we have a small machine which is kept underneath the pockets of your skin maybe the chest. So that will keep your heart rate a little high.
