Late Incidental Discovery of Compression of the Left Anterior The top EKG shows a reading of a person with a healthy heart. Can I undergo another hernioplasty with my heart disease? Respiratory sinus arrhythmia is effectively benign, meaning that it is not harmful. An abnormal ECG can mean many things. - Timing 03:23 The electrical activity of the heart starts at the sinoatrialnode then spreads to the atrioventricular (AV)node. One of the signs of left atrial enlargement on an ECG is an unusual "P wave." If you have this condition, the P wave that represents your atria contracting is longer than normal. Retrieved 2022-10-25., ventricular ectopic arrhythmias, congenital cardiac disease, preexcitation syndrome, pacemaker-generated paced rhythm, conduction abnormalities, mechanical shift, emphysema, normal variation, and hyperkalemia are all examples of these.
