Dysrhythmias II: Classification of Tachyarrhythmias01:28

Dysrhythmias II: Classification of Tachyarrhythmias

283
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...

Imbalances in Cardiac Output01:26

Imbalances in Cardiac Output

1.8K
The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...

Mechanism of Cardiac Arrhythmias

1.4K
Arrhythmias are irregular heart rhythms occurring when the heart's electrical impulses become abnormal. These disturbances can lead to various symptoms, depending on their severity and the underlying cause. Some common factors contributing to arrhythmias include hypoxia, ischemia, electrolyte imbalances, excessive catecholamine exposure, drug toxicity, and muscle overstretching. Arrhythmias can be classified into two main types based on the rate and site of origin of abnormal heart rhythms.

Decreased pulse rate01:14

Decreased pulse rate

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.
There are specific risk factors that can elevate the likelihood of developing bradycardia. Advanced age is a significant factor, with...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

126
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Area of Science:

  • Cardiology
  • Clinical Diagnostics

Background:

  • Palpitations are a common patient complaint.
  • Initial electrocardiogram (EKG) may not reveal the cause.
  • Diagnostic uncertainty requires a structured approach.

Purpose of the Study:

  • To provide a systematic method for evaluating palpitations.
  • To outline essential questions for eliciting diagnostic clues.
  • To offer an algorithm for cases not diagnosed by EKG.

Main Methods:

  • Review of clinical guidelines and diagnostic strategies.
  • Identification of key historical questions for palpitations.
  • Development of a diagnostic algorithm.

Main Results:

  • A comprehensive list of diagnostic questions is presented.
  • A step-by-step algorithm for evaluating palpitations is provided.
  • The algorithm addresses scenarios where initial EKGs are unrevealing.

Conclusions:

  • A structured diagnostic approach improves the evaluation of palpitations.
  • Targeted questioning and a clear algorithm aid in identifying the etiology of palpitations.
  • This framework assists clinicians in managing patients with unexplained palpitations.
