It is so difficult for a person who is not in the medical field to understand, but I will try to explain. Think of your heart as a big bundle of electric pathways. A heart beat normally would start at the top of the bundle and spread thru the AV node ( the middle of the heart) and then go to the bottom of the heart. Then the whole cascade starts over again from the top of the heart to the bottom.
Sometimes the electrical pathways get messed up and instead of the heart beat synchronizing at the top of the heart and going from the top to the bottom, they decide to go thru the wrong pathways and sometime the electrical signals get messed up. When that happens, you get an abnomal heart beat, called an arrythmia. Arrythmias are stimulated by abnormal conduction of the electricity thru the heart.

The normal heart works efficiently by contracting in an orderly fashion - first the atria, then the ventricles. The trigger for this contraction is an electrical impulse.

The electrical impulse normally starts at the "top" of the heart (in the sinoatrial node), travels through the atria, slows down between the atria and the ventricles (at the atrioventricular node), then passes into the ventricles.

If the impulse doesn't follow the normal pattern, it's considered abnormal. This could be anything from a bundle branch block (where the ventricles aren't activated in synch because of a slow-down on one or both sides of the heart), to the impulse traveling from top to bottom but bypassing the atrioventriular node.

Some of these are completely ignorable, some are associated with more concerning things, and some are potentially bad.

The doctor should be able to describe more precisely where the problem is and whether the patient should be concerned.

OK- electricty is was causes your heart to pump (the blood would not go round and round without it). An electrical impulse begins in your SA node, travels to your AV node, down through Bundle of HIS and into your bundle branches.

Any deviation from this is abnormal. Things like SVT, bundle branch blocks, and the more serious ones, like ventricular tachycadia and pulseless electrical activity to name a few. There are many more, far too many to name. Mostly all treatable, with either some form of surgery or medication. Some are really not worth treating if the patient is asymptomatic. Some are never discovered. Wordy, but hope it helped.

heart rate greater than 100 beats per minutes is called a tachycardia. Examples of tachycardias may include a fast, irregular heart rhythm that originates in the ventricle (ventricular fibrillation) or a fast, regular heart rhythm that begins in the atrium (atrial flutter). Abnormal conduction of the electrical impulse in the heart can also be seen in other types of arrhythmias.
