- QUESTION: Could you please explain what S.S.S. (sick sinus syndrome) is, as I
- have finally been diagnosed after fainting in the hospital. The doctors have
- told me that this is my problem. I am now 77 years old, and am doing better
- on medication, but have always tired easily.

- ANSWER: Your present condition, Sick Sinus Syndrome (or Sinus Node
- Dysfunction Syndrome), is most likely completely unrelated to your previous
- fatigued periods, for it is a condition that is more common in older patients.
- It is most frequently seen in patients who have coronary artery disease,
- although there are several other conditions that can cause the problem. And
- the problem is that the sinus node, the principle pacemaker of the heart that
- controls the rhythm and speed of the heart beat, is not functioning as it
- should, probably because it is not getting sufficient blood flow from the
- heart arteries which may be affected by arteriosclerosis (hardening of the
- arteries). When it fails to send out the electrical messages that make the
- heart muscles contract, a heart beat is either skipped or the time between
- heart beats is prolonged. This reduces the amount of blood that is pumped
- through the heart, and reduces the amount of oxygen carried to the brain.
- When this occurs a patient feels weak, dizzy, or may faint and pass out
- completely as in your case. In other cases a sick sinus can begin to send out
- impulses too frequently, and the heart rate is increased, a condition known as
- "tachycardia". While medications can be used to help increase the blood flow,
- an external pacemaker is used to control the heart beat when the sinus node no
- longer may be depended upon to keep the beat strong and regular.
- The diagnosis is usually made with the help of a Holter monitor, a small,
- portable device that keeps a record of the heart action for a 24 hour period.
- When the record is reviewed, the physician can find the irregular heart beats
- that cause the physical symptoms, and evaluate the extent of the problem.
- This helps in choosing the right medication or help to make the decision to
- use a pacemaker instead.
