==Myocarditis==
[[w:Myocarditis|Myocarditis]] is an inflammation of the myocardium and the interstitium. The symptoms are faint chest pain, abnormal heart rate and progressive heart failure. It can be caused by several factors: viruses, bacteria, fungi, parasites, spirochaetesspirochetes, auto-immune reactions, borreliosis (Lyme's disease) and HIV/AIDS.
Acute peri/myocarditis causes nonspecific ST segment changes. These can be accompanied by supraventricular and ventricular rhythm disturbances and T-wave abnormalities.
==Hypertrophic Obstructive Cardiomyopathy==
A HOCM is an a hereditary illness.
On the ECG there are signs of [[hypertrophy|left ventricular hypertrophy]] and [[P wave morphology|left atrial enlargement]].
* Prolonged QTc-interval
* ST segment elevation (inferior and left precordial leads)
* Osborne-waves (slow deflexions deflections at the end of the QRS-complex)

*ST-T segment elevation or depression
