seversdatter - As Mark_the_nurse has noted, the numbers you give are only a small part of the information that can be gleaned from an EKG. More of the information can be determined by analyzing the pattern of waveforms on the EKG. The numbers above are generated by the computer and represent the timing of certain events in the cardiac cycle. - The heart rate of 66bpm is normal. - The PR interval represents the time it takes for a signal to get from your sinoatrial node down to the ventricles. It can be prolonged in patients with disease of the conduction system or shortened in patients with accessory pathways. Yours is normal. - The QRS duration represents the amount of time it takes for an electrical signal to be distributed throughout the ventricles. It can be prolonged in patients with disease of the conduction system or in patients with heart failure, for example. Yours is normal. - The QT interval represents that amount of time it takes for the ventricles to repolarize after they have been activated by a normal electrical impulse. People with prolonged QT intervals may be at risk for arrhythmias and cardiac arrest. Your is normal. - The P, R, and T axes indicate the direction in which the electrical impulse is traveling. Yours are all normal. If you have questions about the EKG itself, it would be better for you to have a physician look at the whole study and review it with you. It is possible for all these numbers to be within the normal range while the overall EKG is still abnormal.
