Rapid wide QRS tachycardia with an unknown cause
1Department of Electrocardiography, Dancheng County Central Hospital, Zhoukou, China.
Summary
Atrial flutter with 1:1 atrioventricular conduction (AVC) can be life-threatening. This case highlights Wolff-Parkinson-White syndrome presenting with rapid 1:1 AVC during atrial flutter, emphasizing the need for prompt diagnosis.
Area of Science:
- Cardiology
- Electrophysiology
- Arrhythmology
Background:
- Atrial flutter with 1:1 atrioventricular conduction (AVC) is a severe, hemodynamically unstable arrhythmia.
- Rapid wide QRS tachycardia can stem from various causes, including ventricular tachycardia, supraventricular tachycardia with QRS prolongation, or preexcitation syndromes.
Observation:
- This case report details an uncommon presentation of Wolff-Parkinson-White syndrome.
- The patient exhibited atrial flutter with rapid 1:1 AVC via an accessory pathway.
Findings:
- The electrocardiogram (ECG) showed a rapid wide QRS complex pattern.
- This pattern is characteristic of atrial flutter with 1:1 AVC in the context of Wolff-Parkinson-White syndrome.
Implications:
- Physicians must recognize the specific ECG findings associated with atrial flutter and 1:1 AVC in Wolff-Parkinson-White syndrome.
- Accurate diagnosis is crucial for guiding appropriate treatment strategies and improving patient outcomes.

134
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...

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...

184
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...

136
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...

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...

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...
