  2. Premature ventricular contraction - Wikipedia

    en.wikipedia.org/wiki/Premature_ventricular...

    PVCs may be perceived as a skipped heart beat, a strong beat, palpitations, or lightheadedness. They may also cause chest pain, a faint feeling, fatigue, or hyperventilation after exercise. [2] Symptoms may be more pronounced at times of stress. Women may be more aware of PVCs at the time of the menstrual period. [2]

  3. Premature heart beat - Wikipedia

    en.wikipedia.org/wiki/Premature_heart_beat

    A premature heart beat or extrasystole [1] is a heart rhythm disorder corresponding to a premature contraction of one of the chambers of the heart. Premature heart beats come in two different types: premature atrial contractions and premature ventricular contractions. Often they cause no symptoms but may present with fluttering in the chest or ...

  4. Arrhythmia - Wikipedia

    en.wikipedia.org/wiki/Arrhythmia

    In adults and children over 15, resting heart rate faster than 100 beats per minute is labeled tachycardia. Tachycardia may result in palpitation; however, tachycardia is not necessarily an arrhythmia. Increased heart rate is a normal response to physical exercise or emotional stress.

    The feeling of your heart pounding or racing is known as heart palpitations. Typically, heart palpitations are not anything to worry about, but there are times when you should see a doctor about them.

  6. Hypertrophic cardiomyopathy - Wikipedia

    en.wikipedia.org/wiki/Hypertrophic_cardiomyopathy

    In individuals with aortic stenosis, after a premature ventricular contraction (PVC), the following ventricular contraction will be more forceful, and the pressure generated in the left ventricle will be higher. Because of the fixed obstruction that the stenotic aortic valve represents, the post-PVC ascending aortic pressure will increase as well.

  7. Heart rate turbulence - Wikipedia

    en.wikipedia.org/wiki/Heart_rate_turbulence

    While studying PVC characteristics, Schmidt and his colleagues noticed that heart rate seemed to speed up after a PVC. To clarify, they listed the time from one heartbeat's R-wave to the next R-wave (called RR intervals) and synchronized these lists to the time of the PVC beat and averaged the values in the list. A plot of this averaged RR ...

  8. Arrhythmogenic cardiomyopathy - Wikipedia

    en.wikipedia.org/wiki/Arrhythmogenic_cardiomyopathy

    Those affected by arrhythmogenic cardiomyopathy may not have any symptoms at all despite having significant abnormalities in the structure of their hearts. [6] If symptoms do occur, the initial presentation is often due to abnormal heart rhythms (arrhythmias) which in arrhythmogenic cardiomyopathy may take the form of palpitations, or blackouts. [7]

  9. Tachycardia-induced cardiomyopathy - Wikipedia

    en.wikipedia.org/wiki/Tachycardia-induced_cardio...

    [1] [5] People with TIC may have symptoms associated with heart failure (e.g. shortness of breath or ankle swelling) and/or symptoms related to the tachycardia or arrhythmia (e.g. palpitations). [ 1 ] [ 2 ] Though atrial fibrillation is the most common cause of TIC, several tachycardias and arrhythmias have been associated with the disease.
