ECG or EKG monitor is a cardiac monitoring medical device for capturing and displaying the electrical activities generated by your heart. By closely examining the electrocardiogram (ECG, EKG) waveform, one can tell a lot about the current heart conditions. The heart's electrical system controls the sequence of events that pumps blood throughout your circulatory system.

Many heart symptoms are transitory and cannot be captured easily anytime by looking at the EKG. Timing is the key. A readily available personal ECG monitor is the best alternative to capture and save the measurement when one is having heart attack symptoms. The data can be further investigated by a doctor later.

The heart's electrical system consists of three main parts:

• The SA (sinoatrial) node, which locates at the top of the right upper heart chamber (atrium) and is the pacemaker that controls the heart beat
• The AV (atrioventricular) node, which locates in the middle of the top and controls the pumping of blood into the body
• The His-Purkinje system, which locates along the heart's ventricle (lower chamber) walls and sends the electrical impulses to the ventricular muscle causing the contraction

A EKG cycle consists of 6 waves: P, Q, R, S, T and U. The P wave is when the atria pump blood into the ventricles; the QRS complex is when the ventricles pump blood into the body; the T wave is when the ventricles relax and getting ready for the next cycle; the U wave is not always present and is typically low amplitude. The frequency, rhythm, waveform, and relative timing of these waves offer important clues to your heart's condition.
