Your ECG is fine ( although the picture quality is not so good) What u had was sinus tachycardia Sinus tachycardia is a normal increase in the heart rate. How it happens - The sinoatrial (SA) node - the heart's natural pacemaker - sends out electrical signals faster than usual. The heart rate is fast, but the heart beats properly. Causes of sinus tachycardia - A rapid heartbeat may be your body's response to common conditions such as: Fever Anxiety Some medicinal and street drugs Severe emotional distress Fright Strenuous exercise Other causes but less commonly, it may indicate: Anemia (low blood count) Increased thyroid activity Heart muscle damage from heart attack or heart failure Hemorrhage (severe bleeding) You may be having Palpitations, which are feelings or sensations that your heart is pounding or racing. They can be felt in your chest, throat, or neck. You may Have an unpleasant awareness of your own heartbeat or may Feel like your heart skipped or stopped beats The heart's rhythm may be normal or abnormal when you have palpitations. Palpitations are not serious most of the time. Sensations representing an abnormal heart rhythm (arrhythmia) may be more serious. Your doctor should consider and treat the cause of sinus tachycardia rather than the condition itself. If your rapid heartbeat is a symptom of a more serious or longer term problem, simply slowing the heart rate without checking for underlying reasons could cause more harm because you are leave the underlying condition untreated. So get a routine health checkup done with echocardiography and CBC & tsh levels.
