What causes electrical problems with the heart?

Many patients have PSVT due to congenital abnormalities in the electrical conduction system of the heart. External causes can include hyperthyroidism, electrolyte imbalances, and the use of caffeine, alcohol, over-the-counter cold medications containing stimulants, or illegal drugs like cocaine and methamphetamine.

What causes conduction disorders?

Arrhythmias and conduction disorders are caused by abnormalities in the generation or conduction of these electrical impulses or both. Any heart disorder, including congenital abnormalities of structure (eg, accessory atrioventricular connection) or function (eg, hereditary ion channelopathies), can disturb rhythm.

Is heart block a conduction disorder?

When you have heart block, there is interference with the electrical signals that usually travel from the atria to the ventricles. This is known as a conduction disorder. If the electrical signals can’t move from your atria to your ventricles, they can’t tell your ventricles to contract and pump blood correctly.

What causes heart conduction problems?

Arrhythmias and conduction disorders are caused by abnormalities in the generation or conduction of these electrical impulses or both. Any heart disorder, including congenital abnormalities of structure (eg, accessory atrioventricular connection) or function (eg, hereditary ion channelopathies), can disturb rhythm.

What is IVCD on EKG?

IVCD stands for intraventricular conduction delay or disturbance. It is a disturbance in the normal conduction of the electical impulses in the heart. It is detected by an EKG which shows widening of the QRS complex.

Is a pulse rate of 47 good?

If you are healthy, a heart rate of 47 is okay, and in some is even good! Many runners we see in clinic have heart rates as low as 47, and it just means that their hearts are strong enough to pump enough blood to the rest of their body by only beating 47 times a minute.

What are the effects of low pulse rate?

If your pulse rate drops too low, you may feel lightheaded, dizzy, confused or very tired. Fainting is also a risk. In severe cases, cardiac arrest or a sudden loss of heart function may occur.
