Summary
Aging shortens telomeres, a marker of biological aging. This study found that while electrocardiogram (ECG) measures change with age, they are not associated with telomere length in a large community cohort.
Area of Science:
- Cardiology
- Genetics
- Gerontology
Background:
- Aging is linked to telomere shortening, a potential marker for biological aging.
- Cardiac aging is associated with pathologies like atrial fibrillation.
- Electrocardiogram (ECG) measures prolong with age and correlate with cardiac issues.
Purpose of the Study:
- To investigate the association between telomere length and ECG measures.
- To determine if premature ECG measure prolongation is linked to telomere shortening.
Main Methods:
- Utilized data from the KORA F4 Study (n=2,575).
- Measured leukocyte telomere length using real-time quantitative PCR.
- Employed multivariable adjusted linear regression to analyze ECG intervals (RR, PR, QRS, QTc) against telomere length.
Main Results:
- Older age and male sex were associated with shorter telomere length.
- Unadjusted analyses showed associations between heart rate, PR-interval, QTc-interval, and shorter telomere length.
- These associations disappeared after adjusting for age, sex, and other covariates.
Conclusions:
- Age-dependent ECG measures are not significantly associated with telomere length.
- Further research is needed to explore the link between telomere length and cardiac pathologies such as atrial fibrillation.

3.2K
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.

Introduction
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.

3.5K
An electrocardiogram (ECG)graphically represents the heart's electrical activity on ECG paper or a monitor.
Components of the Electrocardiogram
The primary components of a normal ECG waveform in Normal sinus rhythm(NSR) include the P wave, PR interval, QRS complex, ST segment, T wave, and occasionally a U wave.
ECG waveforms are divided by vertical and horizontal lines at standard intervals.
The horizontal axis measures time and rate, and the vertical axis measures amplitude or voltage....

239
Holter monitoring is a continuous electrocardiography (ECG) recording that tracks the heart's electrical activity over an extended period, generally 24 to 48 hours. This noninvasive diagnostic tool detects irregular heart rhythms that may not be captured during a standard ECG performed in a clinical setting.DeviceThe Holter monitor is a portable, small device connected to several electrodes on the patient's chest. These electrodes detect the heart's electrical signals and transmit them to the...

01:25Correlation between ECG and Cardiac Cycle
8.2K
The electrical signals recorded on an electrocardiogram (ECG) occur before the mechanical processes of contraction and relaxation during the cardiac cycle.
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...

2.4K
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.
