Heart failure can result from many forms of heart disease including heart defects cardiovascular disease valvular heart disease heart infections or cardiomyopathy.
Electrical heart problems causes.
Pacemakers are also needed when there is electrical block of the signals.
Abnormalities of the heart that result in scarring of heart tissue sometimes called structural heart disease the most common cause is a prior heart attack.
The abnormality can be due to a physical extra electrical pathway such as that seen in wolff parkinson white wpw syndrome or it can be due to changes in.
Heart rhythm problems heart arrhythmias occur when the electrical impulses that coordinate your heartbeats don t work properly causing your heart to beat too fast too slow or irregularly.
A blood clot blocking the blood flow through a blood vessel that feeds the heart causes a heart attack possibly damaging or destroying a part of the heart muscle.
This can cause short circuits making the heart speed up and beat 150 beats a minute or more.
In fact damage to the electrical system of the heart is often the cause of sudden death with a heart attack even if the damage to the heart caused by the heart attack is only.
These impulses travel along a pathway including the right and the left bundles.
If one or both of these branch bundles become damaged due to a heart attack for example this can block the electrical impulses and cause your heart to beat.
Heart problems that affect your breathing heart failure sometimes called congestive heart failure.
Poor blood flow to the heart muscle due to coronary artery disease.
Even though failure is in the name it doesn t mean that your heart stops beating.
However often the slow heart beat cannot be improved by medication adjustments and then a pacemaker is needed.
This may be the situation when the slow heart beat is due to problems with the sinus node sick sinus syndrome.
Rapid heart rates may be due to wiring problems with the electrical pathways in the heart.
Sometimes an irregular heart beat can be improved by adjusting medications.
Many things can cause or contribute to problems with the heart s electrical system.
The heart is controlled by electrical impulses that tell the heart when to send blood out to other parts of the body.
When something goes wrong with the electrical system in the heart it can cause problems that can range from minor to severe.
