14 Possible Causes for Irregular Heart Rhythm, Tachycardia during Pain Episodes

  • Coronary Artery Disease

    The test shows how fast the heart is beating and its rhythm (steady or irregular).[] Transient ST-segment depression and chest pain detected during ambulatory monitoring were usually associated with tachycardia ( Figure 3 ).[] An EKG also records the strength and timing of electrical signals as they pass through the heart.[]

  • Ventricular Tachycardia

    If left untreated, some forms of ventricular tachycardia may get worse and lead to ventricular fibrillation (fast and irregular heart rhythm), which can be life-threatening[] If your heart rate during a ventricular tachycardia episode is extremely rapid or continues for several seconds, you may experience some or all of these symptoms.[] It arises in the heart’s lower chambers (ventricles) from tissues that generate a rapid and irregular heart rhythm.[]

  • Holiday Heart Syndrome

    The irregular rhythm in holiday heart syndrome is best diagnosed with an electrocardiogram. The beats will be irregular all the time.[] During an episode, you may experience symptoms such as: a pounding or fluttering heartbeat ( heart palpitations ) feeling light-headed or dizzy shortness of breath chest pain[] What to be on the lookout for The symptoms of “holiday heart syndrome” stem from an irregular, often fast, heart rhythm.[]

  • Preterm Labor

    But nifedipine is associated with an increased risk of angina, heart attack, congestive heart failure, irregular heart rhythm, oxygen deficiency in the tissues (hypoxia),[] Recurrent episodes of supra-ventricular tachycardia were refractory to medical therapy and required repeated direct current cardioversion.[] Administration of disopyramide led to the initiation of painful uterine contractions and accidental hemorrhage.[]

  • Wolff-Parkinson-White Syndrome

    , rapid, and irregular heart rhythm).[] A child old enough to express himself may complain of chest pain, palpitations, dizziness, lethargy and difficulty in breathing during episodes of tachycardia.[] […] or irregularly) Shortness of breath A physical exam done during a tachycardia episode will show a heart rate faster than 100 beats per minute.[]

  • Variant Angina Pectoris

    The disorder may be a sign that you have a high risk for heart attack or deadly irregular heart rhythms.[] Ventricular premature beats, ventricular tachycardia and one episode of ventricular fibrillation were recorded.[] Individuals presenting with potentially lethal irregularities in the rhythm of their heart beating or a history of episodic fainting spells due to such arrhythmias require[]

  • Bradyarrhythmia

    You may take them to lower blood pressure or for other heart conditions. Sick Sinus Syndrome This type of bradycardia causes an abnormal heart rhythm.[] Other symptoms experienced during an episode of SVT include dizziness, shortness of breath, chest pain, and light-headedness.[] Second-degree heart block. Not all electrical signals reach the ventricles. Some beats are "dropped," resulting in a slower and sometimes irregular rhythm.[]

  • Paroxysmal Supraventricular Tachycardia

    However, the heart's electrical signals spread through the atria in a fast and regular—instead of irregularrhythm.[] Abstract During episodes of paroxysmal supraventricular tachycardia (PSVT), electrocardiograms frequently show ST-segment depressions, and patients may experience typical[] The sister, a 24-year-old woman, had intermittent episodes of palpitation accompanied by chest pain for 2 years.[]

  • Familial Episodic Pain Syndrome Type 1

    Andersen-Tawil syndrome or ATS: People with this type have inconsistent potassium shifts during attacks of paralysis, and may have symptoms of irregular heart rhythms including[]

  • Preexcitation Syndrome

    , rapid, and irregular heart rhythm).[] […] or irregularly) Shortness of breath A physical exam done during a tachycardia episode will show a heart rate faster than 100 beats per minute.[] Arrhythmia Also called: Irregular heartbeat An arrhythmia is a problem with the rate or rhythm of your heartbeat.[]
