What is the difference between a q-wave and non-qwave heart attack?
4 doctors weighed in across 2 answers
Similar: Prognostically, q and non-q wave heart attacks are similar, the difference being whether a Q wave is present, signifying a full muscle thickness damage (q wave) vs. Partial thickness (non q wave) heart attack. The important issue is the amount of heart muscle damaged and residual muscle at risk, affecting heart function (thus symptoms) and risk of arrhythmias. Treatment is basically similar.

Wall Thickness: Q wave= full thickness myocardial necrosis non q wave= partial thickness or subendocardial necrosis subendocardial infarcts more common. Full thickness can result in myocardial rupture or an acute ventricular septal defect. Rupture- tamponade-death sequence. 50% of people still die on their first heart attack mostly because of not calling 911 or reaching er within minutes of the infarct.
