Increased pulse rate01:17

Increased pulse rate

731
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...

ECG Interpretation of Arrhythmias I: Sinus Arrhythmias

380
Arrhythmias are disturbances in the heart's rhythm that lead to abnormal heartbeats. These irregularities can originate from different parts of the heart and are classified based on their origin and nature.
Types of Arrhythmias
Sinus Node Arrhythmias
Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism,...

Dysrhythmias II: Classification of Tachyarrhythmias

128
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...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

38
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...

Rheumatic Heart Disease III: Medical Management

26
Rheumatic heart disease (RHD) management can be divided into two main strategies: prevention and long-term management.Primary PreventionPrimary prevention focuses on timely diagnosis and management of group A streptococcal pharyngitis to prevent acute rheumatic fever. The most widely used antibiotic for treating this condition is intramuscular benzathine penicillin G.Acute Rheumatic Fever TreatmentThe primary treatment goal for a patient diagnosed with acute rheumatic fever is to suppress the...

Dysrhythmias III: Characteristics of Dysrhythmias01:29

Dysrhythmias III: Characteristics of Dysrhythmias

101
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...

  • The approach focuses on a holistic understanding of ST, considering its broad spectrum of presentations and underlying pathologies.

Main Results:

  • Sinus tachycardia (ST) presents a diagnostic challenge due to its diverse origins, ranging from benign physiological responses to indicators of significant underlying pathology.
  • Effective management requires a thorough differential diagnosis, considering conditions like pulmonary embolism, anemia, infection, hyperthyroidism, inappropriate sinus tachycardia, postural tachycardia syndrome, mast cell disorders, and post-COVID conditions.
  • A collaborative, interdisciplinary approach is crucial for accurate diagnosis and optimal treatment of patients experiencing persistent or paroxysmal ST.

Conclusions:

  • Sinus tachycardia (ST) necessitates a broad differential diagnosis and a comprehensive evaluation.
  • Integrating expertise from various medical fields, including cardiology, neurology, and immunology, is essential for a complete understanding and effective management of ST.
