Time for a #tweetorial on simple #ECG interpretation

When I learned to read ECGs, my biggest fear was to miss an important finding!

‼️ All following ECGs are with paper speed of 25 mm/s and a signal gain of 10 mm/mV ‼️

Therefore:
1 small square = 40 ms
1 big square = 200 ms

Now we are ready to read the ECG systematically

1⃣ Rhythm

Sinus rhythm or abnormal rhythm?
(Also note if regular or irregular)

Normal: One P-wave precedes each QRS complex (sinus rhythm)

Interpret from the lead that shows the P-wave most clearly (usually lead II)
