What're the symptoms of sick sinus syndrome?
A patient may not show any symptoms of sick sinus syndrome. In general, however, the common symptoms are those associated with slow heart rate, such as light-headedness, or dizziness , fatigue and fainting. Patients may also experience confusion, heart palpitations , angina or heart failure.
Many people with sick sinus syndrome have no symptoms, or the symptoms may not seem serious enough for concern. The condition may not be diagnosed until it is in an advanced stage. Typically, the first sign an individual with SSS notices is a consistently slow heart rate or bradycardia. Often, the rate falls to 40 to 50 beats per minute or less before it is noticed.
