Dysrhythmias III: Characteristics of Dysrhythmias01:29

Dysrhythmias III: Characteristics of Dysrhythmias

13
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...

Dysrhythmias II: Classification of Tachyarrhythmias

13
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...

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

55
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...

Increased pulse rate01:17

Increased pulse rate

703
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...

Pulse rhythm01:30

Pulse rhythm

857
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

Disturbances in Heart Rhythm01:29

Disturbances in Heart Rhythm

1.0K
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...

Area of Science:

  • Cardiology
  • Electrophysiology

Background:

  • Ventricular tachycardia (VT) is a significant cardiac arrhythmia originating in the heart's ventricles.
  • It is characterized by a QRS complex exceeding 120 milliseconds and a heart rate over 100 bpm on an electrocardiograph.
  • VT can present as either a pulsed or pulseless rhythm, with pulseless VT leading to absent cardiac output.

Observation:

  • Pulsed VT may present with asymptomatic patients or symptoms indicative of reduced cardiac output due to impaired ventricular filling.
  • Patients with pulsed VT can rapidly deteriorate hemodynamically if not promptly managed.
  • This article focuses on a specific case of pulsed VT managed outside of standard hours in an acute care environment.

Findings:

  • The case involved the diagnosis of pulsed ventricular tachycardia.
  • Timely intervention and treatment were administered during out-of-hours care.
  • Successful management of pulsed VT in an acute hospital setting was achieved.

Implications:

  • Effective management of pulsed VT, even during out-of-hours periods, is crucial for patient outcomes.
  • Prompt diagnosis and treatment are essential to prevent hemodynamic instability.
  • This case highlights the importance of accessible emergency cardiac care for arrhythmias.
