Disturbances in Heart Rhythm01:29

Disturbances in Heart Rhythm

1.5K
Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow heart...

Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...

Dysrhythmias III: Characteristics of Dysrhythmias

146
Dysrhythmias, also known as arrhythmias, are irregular heart rhythms that result from abnormal electrical activity in the heart, affecting its ability to circulate blood efficiently. Tachyarrhythmias, a subset of dysrhythmias, are characterized by abnormally fast heart rates exceeding 100 beats per minute. Here are some types of tachyarrhythmias with their distinct ECG features:Sinus Tachycardia:Sinus tachycardia presents a regular heart rhythm with an increased rate of 101-180 beats per...

Mechanism of Cardiac Arrhythmias

1.1K
Arrhythmias are irregular heart rhythms occurring when the heart's electrical impulses become abnormal. These disturbances can lead to various symptoms, depending on their severity and the underlying cause. Some common factors contributing to arrhythmias include hypoxia, ischemia, electrolyte imbalances, excessive catecholamine exposure, drug toxicity, and muscle overstretching. Arrhythmias can be classified into two main types based on the rate and site of origin of abnormal heart rhythms.

Dysrhythmias II: Classification of Tachyarrhythmias

152
Tachyarrhythmias are a type of dysrhythmia where the heart rate exceeds 100 beats per minute. Here are some common types of tachyarrhythmias:Sinus TachycardiaSinus tachycardia originates from increased impulses from the sinus node, leading to an elevated heart rate. It is often triggered by stress, fever, or exercise.Patients may experience palpitations, a sensation of a racing heart, dizziness, and chest discomfort.Causes and Risk Factors: Common causes include physical exertion, emotional...

Dysrhythmias I: Introduction

183
Dysrhythmias refers to abnormalities in the heart's rhythm. They result from disruptions in the heart's electrical conduction system, which includes the sinoatrial(SA)node, atrioventricular(AV) node, the bundle of His, bundle branches, and Purkinje fibers.Definition and PathophysiologyDysrhythmias result from disorders of impulse formation, impulse conduction, or both. The heart contains specialized cells in the sinoatrial node, atrioventricular node, and the bundle of His and Purkinje fibers...

Area of Science:

  • Cardiology
  • Maternal-Fetal Medicine
  • Electrophysiology

Background:

  • Maternal mortality and arrhythmia incidence, including atrial fibrillation, are rising in the US.
  • Pregnancy elevates arrhythmia risk, particularly for those with pre-existing conditions.

Purpose of the Study:

  • To review current management strategies for tachyarrhythmias and bradyarrhythmias during pregnancy.
  • To discuss the treatment of cardiac arrest and fetal arrhythmias.
  • To highlight the need for integrated care in managing arrhythmias in pregnant individuals.

Main Methods:

  • Literature review of studies on pregnancy and arrhythmias.
  • Analysis of treatment options for maternal and fetal arrhythmias.
  • Discussion of procedural interventions and device implantation during pregnancy.

Main Results:

  • Beta-blockers (propranolol, metoprolol) and antiarrhythmics (flecainide, sotalol) are safe for treating tachyarrhythmias in pregnant patients without structural heart disease.
  • Catheter ablation and device implantation are feasible with minimal fluoroscopy and appropriate guidance.
  • Fetal arrhythmias also have specific management considerations.

Conclusions:

  • A multidisciplinary approach is crucial for managing arrhythmias throughout pregnancy and postpartum.
  • Rising maternal age and comorbidities necessitate proactive and integrated arrhythmia care.
  • Timely and appropriate management can mitigate risks associated with arrhythmias in pregnancy.
