This is often (but not always) seen on ordinary ECG tracings and it is explained by the fact that the atria are depolarized sequentially, with the right atrium being depolarized before the left atrium. As forventricular enlargement, the ECG cannot differentiate dilatation from hypertrophy, which is why some experts have suggested that the termatrial abnormality be used instead of enlargement.

Based on a work athttps://litfl.com. Note that patients with chronotropic incompetence may require pacemaker to increase exercise capacity and reduce symptoms. It is very common that patients with bradycardia have a strong indication for drugs that aggravate or even cause the bradycardia; in such scenarios, it is generally considered to be evidence based to implement an artificial pacemaker that will allow for drug therapy to continue.
