What is a sinus rhythm in ECG?
Sinus rhythm (a.k.a. normal sinus rhythm) refers to the normal heart beat originating from the sinoatrial node. This is manifested as an upright P wave in lead II of the ECG.
What does a good sinus rhythm look like?
When a person has a normal sinus rhythm on their EKG, these beats are in a regular, orderly rhythm. Each should look like the previous and will be as evenly spaced with each other. An EKG of a person with A-fib is very different in its appearance when compared with sinus rhythm.

What does sinus tachycardia look like on ECG?
Sinus tachycardia is recognized on an ECG with a normal upright P wave in lead II preceding every QRS complex, indicating that the pacemaker is coming from the sinus node and not elsewhere in the atria, with an atrial rate of greater than 100 beats per minute.
What happens if sinus tachycardia is left untreated?
But if left untreated, tachycardia can disrupt normal heart function and lead to serious complications, including: Heart failure. Stroke. Sudden cardiac arrest or death.
When should I worry about sinus tachycardia?
In some patients, sinus tachycardia may indicate other concerns, such as increased thyroid activity, anemia, damage to the heart muscle due to a heart attack, or severe bleeding. An isolated occurrence of sinus tachycardia in response to an identifiable trigger may not require medical attention.
