Summary
Increased epicardial adipose tissue (EAT) volume is associated with PR-interval prolongation. This finding highlights a potential link between EAT and cardiac conduction abnormalities.
Area of Science:
- Cardiology
- Radiology
- Biomedical Engineering
Background:
- Epicardial fat (EAT) is inflammatory visceral adipose tissue.
- Obesity and inflammation are linked to cardiovascular disease and arrhythmias.
- The relationship between EAT and PR-interval prolongation is not well understood.
Purpose of the Study:
- To investigate the association between epicardial adipose tissue (EAT) volume and PR-interval prolongation.
- To utilize computed tomography (CT) and Twelve-lead ECGs for assessment.
Main Methods:
- 287 patients referred for CT for coronary artery disease exclusion.
- EAT volumes determined by 64-slice CT.
- Twelve-lead ECGs evaluated by two independent readers.
Main Results:
- Patients with PR-interval prolongation had higher median EAT volume.
- Significant correlations found between EAT volume and PR interval (p = 0.003) and QRS duration (p = 0.018).
- EAT volume >144.4 cm³ was associated with PR-interval prolongation.
Conclusions:
- EAT volume is strongly associated with PR-interval prolongation.
- Further research is needed to determine EAT's role in the pathogenesis of PR-interval prolongation.

Location and Orientation of the Heart
14.8K
The human heart, despite its modest size and weight, is an organ of remarkable strength and endurance. Roughly the size of a fist, the heart weighs between 250 and 350 grams and is nestled within the mediastinum, the medial cavity of the thorax. It extends obliquely for about 12 to 14 cm, resting on the superior surface of the diaphragm. The heart is positioned anterior to the vertebral column and posterior to the sternum, with two-thirds of its mass lying to the left of the midsternal line.

Electrocardiogram
9.0K
An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.

Heart Failure II: Pathophysiology
1.5K
Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Cardiac Action Potential
10.3K
Cardiac action potentials are essential for proper heart function, enabling the rhythmic contractions needed for adequate blood circulation. Nodal cells and Purkinje fibers, specialized for electrical conduction, generate these action potentials.
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.
