|---|---|
| subendocardial myocardial infarction | Infarction that involves only the layer of muscle subjacent to the endocardium. (05 Mar 2000) |
| nontransmural myocardial infarction | Necrosis of heart muscle that fails to extend from the endocardium to the epicardium, often erroneously considered relatively benign. (05 Mar 2000) |
| diaphragmatic myocardial infarction | Infarction in which the inferior or diaphragmatic wall of the heart is involved, producing indicative changes in leads II, III, and aVF in the electrocardiogram. Synonym: diaphragmatic myocardial infarction. (05 Mar 2000) |
| infarction | 1. <cardiology> The formation of an infarct. 2. An infarct. Origin: L. Infarcire = to stuff in (18 Nov 1997) |
| inferior myocardial infarction | Infarction in which the inferior or diaphragmatic wall of the heart is involved, producing indicative changes in leads II, III, and aVF in the electrocardiogram. Synonym: diaphragmatic myocardial infarction. (05 Mar 2000) |
| inferolateral myocardial infarction | Infarction involving the inferior and lateral surfaces of the heart and producing indicative changes in the electrocardiogram in leads II, III, aVF, V5, and V6. (05 Mar 2000) |
| through-and-through myocardial infarction | Infarction that involves the whole thickness of the heart muscle from endocardium to epicardium. Synonym: through-and-through myocardial infarction. (05 Mar 2000) |

| arrhythmias, atrial | Abnormal heart rhythm due to electrical disturbances in the atria (the upper chambers of the heart) or the AV node relay station , leading to fast heart beats. Examples of atrial arrhythmias includes atrial fibrillation, atrial flutter, and paroxysmal atrial tachycardia (PAT). (12 Dec 1998) |
| atrial | <anatomy> Pertaining to an atrium. (16 Dec 1997) |
