Bradycardia

• A heart rate that is too slow is referred to as
  a condition known bradycardia. In some of the
  cases, it may seem like the heart is skipping a
  beat from time to time.The heart rhythm of
  well-trained athletes can be very slow without
  any prior health problem as their hearts are more
  efficient than the hearts of non-athletes. They
  are able to pump the same amount of blood into
  the body with fewer heartbeats.Bradycardia can
  be a severe health issue, if the heart rate fails
  to supply the body with the needed blood and
  oxygen.In some types of bradycardia, the blood
  supply is sufficient at rest, but the heart rate
  isnt able to adapt to situations of physical or
  emotional stress. This failure to adapt the heart
  rate is known as chronotropic incompetence.

What causes Bradycardia?

• Diseases, injuries or scar tissue can cause
  problem to the hearts natural pacemaker, the
  sinus node, causing the heartbeat to slowdown.
  This disorder of the impulse generating system is
  called sick-sinus-syndrome.In sick-sinus
  syndrome, bradycardia and tachycardia (heart beat
  which is too fast) may alternate, especially in
  the atria, or upper chambers of the heart.If
  the heart rate doesnt accelerate in stressful
  situations because of chronotropic incompetence,
  this is also generally a consequence of a damaged
  sinus node.Another potential cause of
  bradycardia is a disorder of the impulse
  conduction system, e.g., so-called heart block or
  atrioventricular block.In an atrioventricular
  block, the impulse conduction between atrium and
  ventricle is delayed or blocked, resulting in a
  heartbeat which too slow.Risk factors for
  bradycardia increase with age and coronary artery
  disease progression.

How is Bradycardia diagnosed?

• The physician makes a diagnosis on the basis of
  the patients symptoms, the findings of a
  physical exam and the results of an
  electrocardiogram. The ECG measures the hearts
  activity and is used to diagnose episodes of
  bradycardia.In case of doubt or if the safety
  of the patient requires it, long-term monitoring
  of the hearts activity may be indicated.If the
  findings of a long-term ECG (Holter Monitoring)
  are not sufficient, the implant of a subcutaneous
  cardiac monitor may be useful to monitor the
  heart over a longer period of time.

• The procedure to implant this small device is
  ambulatory and very short. BioMonitor 2 enables
  continuous remote monitoring of the hearts
  activity.The physician is able to detect
  whether the patient suffers from an arrhythmia
  and to identify causes for as yet undiagnosable
  fainting (syncope).

What are the symptoms of Bradycardia?

• Patients with chronic bradycardia complain of
  decreasing strength and endurance, poor
  concentration, temporary disorientation and
  dizziness. Dizziness, the feeling of being near a
  blackout and even fainting (syncope) may occur
  suddenly.
