Cardiac anaesthesia can be boring as hell. On the upside, there is no better way to get a true understanding of cardiac physiology than directly observing, actually seeing, what the heart does.

This is what VF, cardioversion and sinus rythm really look like.

This patient had hypothermic cardioplegia for cardiac surgery. Surgery was performed at a core temperature around 27°C with a heart in ventricular fibrillation. Then we started rewarming. At 30°C the heart was still fibrillating but was still too cold to be shocked into a sinus rhythm. The video below is shot at about 32°C. After the second shock the heart cardioverts from hopeless non-perfusing VF into glorious SR.

    Wow. Wow. Wow. This is amazing footage. So great to see it happening to the actual heart muscle, and not have to imagine what is happening inside. So cool.
