One idea about the heart, every Sunday
How your heart works, in plain words
A short letter from Dr Ong on how the heart and circulation work, in words you can read with your coffee.
Earlier letters
One idea about the heart at a time.

The four rooms of the heart
Two small rooms on top, two big ones below, and the doors between them.

The heart as a kopitiam
Orders come in, orders go out, and the stall never closes.

A talk at the void deck, with questions
What people asked last Thursday, and how I answered each one.

About
Ong Kah Hwee
I have been a cardiologist for thirty-four years. I grew up in Toa Payoh, trained in Singapore and spent most of my working life on a hospital cardiology ward. I now see people two days a week.
Most of what I do these days is explain. I give talks at community clubs and senior activity centres, draw the heart on a whiteboard and answer every question. The weekly letter does the same on paper. None of it replaces a visit with your own doctor.
He draws it on the whiteboard, and for the first time I understood how the heart works.
