Insights

Hypertension increases left atrial volume and impairs active emptying function, raising the risk of paroxysmal atrial fibrillation (PAF). A longer duration of hypertension is also linked to PAF in patients.

Area of Science:

  • Cardiology
  • Electrophysiology
  • Hypertension Research

Background:

  • Hypertension is a primary modifiable risk factor for atrial fibrillation.
  • Left atrial pressure overload causes changes in contractile and electrical properties, leading to atrial fibrillation.
  • Understanding these changes is crucial for preventing and managing atrial fibrillation.

Purpose of the Study:

  • To evaluate left atrial function in hypertensive patients.
  • To determine the association between left atrial function and paroxysmal atrial fibrillation (PAF).

Main Methods:

  • Studied 57 hypertensive patients (30 with PAF, 30 controls).
  • Measured left atrial volumes (LAVmax, LAVpreA, LAVmin) using the modified Simpson's biplane method.
  • Calculated various left atrial emptying functions and emptying fractions.

Main Results:

  • Hypertensive patients with PAF had a longer duration of hypertension.
  • Maximal left atrial volume (LAVmax) was significantly increased in hypertensive patients with PAF.
  • Left atrial active emptying function (LAAEF) and A' wave were significantly decreased in hypertensive patients with PAF.

Conclusions:

  • Increased left atrial volume and impaired active emptying function are associated with PAF in hypertensive patients.
  • A longer hypertensive period is a significant risk factor for developing PAF.

Disturbances in Heart Rhythm

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...

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

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

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...

Dysrhythmias IV: Characteristics of Bradyarrhythmias

Bradyarrhythmias are cardiac rhythm disorders characterized by a slower-than-normal heart rate, typically defined as fewer than 60 beats per minute. Some of which are discussed here:Sinus BradycardiaSinus bradycardia presents a heart rate lower than 60 beats per minute, with a regular rhythm originating from the SA node. The ECG typically shows normal P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and a normal QRS duration (0.06 to 0.10 seconds).First-Degree AV...

Mechanism of Cardiac Arrhythmias01:28

Mechanism of Cardiac Arrhythmias

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

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...
