Can left ventricular hypertrophy occur suddenly? From like an infection or is it only gradual?

Not usually sudden. Hypertrophy is enlargement of the hart muscle. It can be a normal response (like to athletic conditioning), or due to abnormalities in the muscle that leads to the hyper trophy. Either way it develops over time. It is seldom, if ever, related to an infection. Infections are more likely to lead to dilation of the heart, not hypertrophy.
Yes. Gradual LVH is mostly from hypertension or heart valve problems. Lvh can occur more rapidly in conditions like hypertrophic cardiomyopathy (commoner), or "infiltrative" conditions where abnormal substances are deposited in the heart muscle (rarer). However, I am not aware of an infectious cause of lvh.

My ECG showed I may have left ventricular hypertrophy. Can I still work out normally if I have it. And any suggestions please.?

Probably, BUT. Most important to know WHY u have LVH. There are a number of causes, HTN being the most common, and this should be treated optimally before working out. Another cause is valve heart disease. If present this should be checked out completely before it is decided that it safe for u to exercise. So, bottom line, see your doc first. Read more...

Left ventricular hypertrophy mild...what are the chances of sudden cardiac death? Thanks

LVH . Any degree of LVH remains a risk for arrhythmia and sudden cardiac death, although the risk is higher with degree of LVH, age and other cardiac risk factors. In one study, the risk of sudden cardiac death was 7%, particularly in the setting of atrial fibrillation. Treating hypertension, weight loss, alcohol cessation may reverse LVH and reduce risks of arrhythmia. . Read more...

My father has undergone 2d echo procedure, it says left ventricular hypertrophy. What should we do?

BP control . Most common cause of LVH is high blood pressure. Control of BP is very important. There are other causes such as genetics however much less common. If thickness is severe, further treatments may be tecommended. Read more...
