The electrocardiogram in infratentorial infarcts
Insights
Electrocardiogram (ECG) abnormalities are common in patients with infratentorial infarcts, but these changes are coincidental. The brain-stem lesion itself does not directly cause ECG alterations, indicating shared underlying vascular disease.
Area of Science:
- Neurology
- Cardiology
- Vascular Medicine
Background:
- Infratentorial infarcts can affect various neurological functions.
- Electrocardiographic (ECG) abnormalities are sometimes observed in patients with central nervous system lesions.
Purpose of the Study:
- To investigate the association between infratentorial infarcts and electrocardiographic (ECG) abnormalities.
- To determine if the localization of brain-stem lesions correlates with specific ECG patterns.
Main Methods:
- Retrospective analysis of 69 patients with infratentorial infarcts.
- Detailed review of electrocardiographic (ECG) findings in all studied patients.
Main Results:
- Approximately 70% of patients exhibited ECG abnormalities.
- Common ECG changes included arrhythmias, conduction disturbances, and ST-T wave alterations.
- No correlation was found between the specific location of the brain-stem lesion and the observed ECG patterns.
Conclusions:
- Ischaemic lesions in the central nervous system do not directly cause ECG changes.
- Associated ECG abnormalities in infratentorial infarct patients likely reflect a common underlying vascular pathology rather than a direct causal link.
- Further research into shared vascular risk factors is warranted.
Abstract:
Sixty-nine patients with infratentorial infarcts were studied with respect to associated electrocardiographic (ECG) abnormalities. ECG changes were encountered in about 70% of the patients, the most frequent abnormalities being arrhythmias, conduction disturbances and ST-T changes. No relationship was found between the localization of the brain-stem lesion and the accompanying ECG pattern. It is concluded that ischaemic lesions within the central nervous system do not per se affect the ECG and that associated ECG changes are merely coincidental, reflecting the same basic vascular disease.

01:25Correlation between ECG and 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...

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.

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.

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. When...
