00:00:00 Introduction
00:01:31 Heart structure and concept of heart cycle

Components of first heart sound S1
Does the opening of valves produce sound?
Opening snap, clicks

The first heart sound (S1) represents closure of the atrioventricular (mitral and tricuspid) valves as the ventricular pressures exceed atrial pressures at the beginning of systole (point a). S1 is normally a single sound because mitral and tricuspid valve closure occurs almost simultaneously.

This is the best explanation of heart sounds I've heard so far. I wish Dr Najeeb had been my tutor when I was a medical student all those decades ago. His lectures are a must for all medical students & even qualified doctors - it is never too late to learn or refresh your understanding. Thank you Dr Najeeb.

[edmondmuthee]

This man Dr.Najeeb ....may God bless you. Your explaining is legendary level!!

[MatirManush-wucc]

If I would not find Prof. Dr. Najeeb I would never be able to become a real doctor. Before I found him I was just a doctor, not a real doctor. The pleasure of becoming a real doctor is like entering into the paradise. We all have an idea of how will be the heaven and hell. Believe me, if you are not being educated medical sciences by Professor Najeeb you are surely in medical hell, not in medical education.

I am addicted to listening the lectures of Prof. Najeeb. Even after acquiring my degree I listen to his lectures nonstop everyday.
