Increased vagal tone (e.g., sinus bradycardia, first degree atrioventricular block [AVB]) and increased chamber size due to physiologic remodeling (e.g., left ventricular hypertrophy [LVH], bi-atrial enlargement) account for normal ECG patterns seen in highly trained athletes. Barlow's syndrome, balloon mitral valve, or floppy valve syndrome, Possible left atrial enlargement is a nonspecific finding which is commonly seen in 12 lead EKG. These ECG changes, including T-wave inversions, can often return to normal with detraining (see below ECGs); outside the context of age <16 years and black ethnicity, T wave inversions beyond V2 should be investigated.

Mitral valve prolapse, also known as click-murmur syndrome, Additional procedures may include: Stress test (also called treadmill or exercise ECG). This may be due to pulmonary valve stenosis, increased pulmonary artery pressureetc. Anterior wall infarctions, on the other hand, generally leave permanent bradycardia and thus demand permanent pacemaker. These symptoms include: Fainting. The P-wave will display higher amplitude in lead II and lead V1. The Framingham Heart Study. A test that records the electrical activity of the heart, shows abnormal rhythms (arrhythmias or dysrhythmias), and can sometimes detect heart muscle damage. Note that sinus bradycardia due to ischemia located to the inferior wall of the left ventricle is typically temporary and resolves within 12 weeks (sinus bradycardia due to infarction/ischemia is discussed separately).
