The ECG shows a negative QRS complex in I (and thus a right [[heart axis]]) and a positive QRS complex in V1. | The ECG shows a negative QRS complex in I (and thus a right [[heart axis]]) and a positive QRS complex in V1. | ||
*R > S in V1 | *QRS duration < 120ms | ||
*Right | *Right [[heart axis]] (> 110 degrees) | ||
* Dominant R wave: | |||
