Bradycardia, also known as bradyarrhythmia, is a slow heart rate, namely, a resting heart rate of under 60 beats per minute (BPM) in adults.It is a type of cardiac arrhythmia. It seldom results in symptoms until the rate drops below 50 BPM.
Bradycardia can cause dizziness, weakness, lack of energy or fainting spells.If bradycardia is caused by a medical illness, there will be additional symptoms that are specific to that illness. For example, people whose bradycardia is due to severe hypothyroidism also can have constipation, muscle cramps, weight gain (often despite poor appetite), very dry skin, hair that is thin and dry, an abnormal sensitivity to cold temperatures and other symptoms related to low levels of thyroid hormones.
Patients are test driving a pacemaker outside the skin before deciding whether to have a permanent implant, reveals novel research presented today at EHRA EUROPACE - CARDIOSTIM 2015."Patients have numerous concerns, such as body image issues. There will be an incision in the upper chest, perhaps some discolouration of the skin and a lump which may be visible depending on what you wear. In women there are intimacy issues with upper chest device implants and usually consider a submammary location.
In sportsmen, there are electrocardiographic manifestations that should not cause concern, because they are part of the so-calledECG pattern of athlete’s heart, that is to say, if present it is not necessary to investigate,should rest assured. They are:sinus bradycardia (present in >50% of cases); very frequent physical or respiratory sinus arrhythmia, first degree AV block (observed in 5% to 30% of the cases in athletes, while in non-athletes it is only 0.65%); possible AF in sportsmen practicing enduro or endurance sports; Mobitz type I or Wenckebach second degree AV block, present in up to 10% of the cases of athletes and only <1 in 30,000 or 0.003% in non-athletes. Characterized by disappearing during exercise and atropine, QRS with notch in ascending ramp of S wave in V1 or IRBBB pattern is observed in 15% of athletes; benign early repolarization pattern is present in 70% of cases, isolated voltage criteria for LVH/LVE (example, Sokolow Lyon +), possible pattern of RVH /RVE: RV1+SV5 >10.5 mm among 18% and 69% of cases. The presence of any of these electrocardiographic manifestations should not make us think of underlying pathology among athletes.
