In a normal heart there is no need of any pacemaker as it has the natural rhythm and heart beat regulation. But if there is problem in heart beats then a pacemaker is used to correct the problem.
Pacemaker is a small device meant to regularize the heart beats by sending electrical impulses to the muscle of the heart. And with this the heart is able to maintain the deserved rhythm. Often a pacemaker is also used in treating heart disease like hypertrophic cardiomyopathy and congestive heart failure.
Implantation of pacemakers has to be done by a surgeon and it is supposed to be implanted under the chest's skin through a small surgery or a procedure. Leads and pulse generator are the two main parts of the pacemaker. Impulses are sent from the pulse generator and with each such impulse there is contraction of the heart. The number of leads differs and depends on the heart problems and range from 1-3.
While you are planning to get the pacemaker implanted you must talk to the doctor about every detail. Talk to him about the medications that you take. Also let him know if you are suffering from any ailment like diabetes. You will be required to stop having food and water 8-10 hours before the procedure.
When does one have diastolic heart failure?
Diastolic heart failure to a medical condition of the heart when the ventricle in the left side of the heart loses the ability of relaxing and thereby stiffens. The cardiac cycle has been classified into two parts. These are known systole and diastole. The systole is the first phase of the cardiac cycle. The ventricles are considered as the major pumping chambers of the heart. During the phase of systole the ventricles pump out blood from the heart. This blood gets in to the arteries. After contracting the ventricles relax. While relaxing, the ventricles again get filled with blood. The filling back with blood prepares them for the next phase of contraction. This phase is known as diastole. When one suffers from diastole heart failure the ventricles of the heart stiffen. As a result of which they cannot relax during the phase of diastole. When this condition appears the ventricle will be unable to be refilled with blood for the next contraction phase. The blood then can be blocked in certain organs of the body, especially in the lungs. This unusual stiffening of ventricle is referred to as diastolic dysfunction. Sometimes the diastolic dysfunction may create pulmonary congestion. This case is termed as diastolic heart failure.
