Summary
Tachycardia upon admission is a negative predictor for stroke outcomes, particularly in hemorrhagic stroke. Medial lesion localization significantly impacts tachycardia occurrence and lethal stroke outcomes.
Area of Science:
- Neurology
- Cardiology
- Stroke Medicine
Background:
- Stroke, both hemorrhagic and ischemic, carries significant mortality risks.
- Understanding factors influencing stroke outcomes is crucial for patient management.
Purpose of the Study:
- To investigate the impact of tachycardia on stroke outcomes.
- To correlate tachycardia with lesion localization in stroke patients.
Main Methods:
- A cohort of 544 stroke patients admitted between March 2015 and January 2016 were analyzed.
- Electrocardiograms (ECGs) were used to detect tachycardia on admission and on the third day of hospitalization.
- Statistical analysis was performed to assess correlations between tachycardia, lesion location, and outcomes.
Main Results:
- Tachycardia on admission was significantly associated with poorer outcomes in both hemorrhagic and ischemic stroke groups (p <0.01).
- In hemorrhagic stroke, tachycardia was more frequent in patients with loss of consciousness.
- Medial lesions were statistically more often associated with paroxysmal tachycardia (p <0.01) and higher mortality rates.
Conclusions:
- Tachycardia at admission is a significant negative predictor of stroke outcome.
- Medial lesion localization is a key factor influencing tachycardia and increasing the risk of lethal stroke, especially in hemorrhagic cases.

Tachycardia is a condition marked by an abnormally fast or irregular heart rate, surpassing the typical resting rate. In adults, tachycardia is characterized by a pulse rate ranging from 100 to 180 beats per minute. The increased heart rate can result in inadequate blood flow to various body parts, ultimately diminishing the oxygen supply to organs and tissues.
Many factors can elevate the risk of developing tachycardia. These include advanced age, a family history of arrhythmias, and an...

Bradycardia is a medical condition in which the heart rate is slower than normal. It occurs when the heart's natural pacemaker, the sinus node, generates slower electrical impulses than the standard rhythm. In adults, bradycardia is diagnosed when the pulse rate falls below 60 beats per minute, indicating a deviation from the normal heart rate range.

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...

01:27Regulation of Stroke Volume
5.4K
The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...

3.9K
Cardiac output (CO), the amount of blood the heart pumps per minute, is a parameter in cardiovascular physiology determined by stroke volume and heart rate. Stroke volume, the amount of blood pushed from one of the ventricles per heartbeat, is influenced by preload, afterload, and contractility.
Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...

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...
