the 2 lower chambers of the heart
Ventricular fibrillation, and supraventricular or ventricular tachycardia.
LVH (Left Ventricular Hypertrophy) is (anatomical) structural condition and status of the heart, while Left Ventricular Dysfunction is disturbance in physiological functions and status of heart.

heart arrhythmias usually of the more dangerous kind. Like ventricular tachycardia and ventricular fibrillation.
Ventricular tachycardia is an abnormal heart rhythm in which the heart beats rapidly due to electrical stimulation coming from the ventricle.
Most ventricular tachycardias are associated with serious heart disease such as coronary artery blockage, cardiomyopathy, or valvular heart disease.
There are three types of heart rhythms and they include; Supraventricular arrhythmias,Ventricular arrhythmias,Bradyarrhythmias.
On an ECG the heart rate will match both ventricular rate and atrial rate if the heart is normal. If people have atrial fibrilation then the ventricular rate will be used on the ECG to work out the rate of the ventricular contraction and vice-versa with ventricular fibrilation. Usually both atrial and ventricular rates match so if the atria contracts at 70 BPM the ventricles will beat at 70 BPM. It is possible for the ECG machine to work out atrial or ventricular rate if needs be. Usually, however, if the ECG machine just displays heart rate then both ventricular and atrial rates match.
Ventricular
Premature ventricular contractions (PVCs) are extra heartbeats that begin in one of your heart's two lower pumping chambers (ventricles). These extra beats disrupt your regular heart rhythm, sometimes causing you to feel a fluttering or a skipped beat in your chest. Premature ventricular contractions are common — they occur in many people. They're also called: Premature ventricular complexes Ventricular premature beats Ventricular extrasystoles If you have occasional premature ventricular contractions, but you're otherwise healthy, there's probably no reason for concern, and no need for treatment. If you have frequent premature ventricular contractions or underlying heart disease, you might need treatment.
A healthy lifestyle to reduce the risk of heart diseases which lead to ventricular fibrillation is the best prevention.
