What can deviations from normal sinus rhythm in an ECG tracing indicate?

Deviations from normal sinus rhythm in an ECG tracing can indicate potential heart abnormalities. Sinus rhythm reflects the normal electrical activity of the heart and ensures efficient pumping of blood. When the rhythm deviates from this norm, it can suggest issues such as arrhythmias, ischemic heart disease, or other cardiac dysfunctions.

By identifying these deviations, healthcare providers can assess the underlying causes, which may require further evaluation or intervention. Recognizing abnormal rhythms is crucial for diagnosing conditions that might not yet be presenting with physical signs or symptoms, thus allowing for early treatment.
