Increased pulse rate01:17

Increased pulse rate

692
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...

Dysrhythmias II: Classification of Tachyarrhythmias

11
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...

Dysrhythmias III: Characteristics of Dysrhythmias

12
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...

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...

Cardiomyopathy VII: Pre and Post Operative Nursing Management

16
Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

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...

Summary

Maternal tachycardia in the postpartum period has many causes. A three-step assessment (Bedside, Basic, Extra) helps clinicians identify serious conditions like peripartum cardiomyopathy.

Area of Science:

  • Obstetrics and Gynecology
  • Cardiology
  • Critical Care Medicine

Background:

  • Maternal tachycardia is a common postpartum sign with diverse etiologies.
  • Current guidelines lack a unified definition, complicating diagnosis and management.
  • Association with adverse outcomes, including mortality, necessitates prompt and accurate assessment, especially with conditions like peripartum cardiomyopathy.

Approach:

  • Proposes a structured three-step assessment model: 'BEDSIDE' (observations, history, examination), 'BASIC' (ECG, basic blood tests), and 'EXTRA' (further investigations).
  • Aims to systematically evaluate postpartum patients presenting with tachycardia.
  • Facilitates differentiation of common sinister causes such as tachyarrhythmias, obstetric hemorrhage, sepsis, venous thromboembolism, and peripartum cardiomyopathy.

Key Points:

  • Physiological changes during pregnancy and postpartum can obscure tachycardia interpretation.
  • The proposed model aids in rationalizing the need for invasive investigations.
  • Standardized assessment can improve diagnostic accuracy and patient care.

Conclusions:

  • The three-step approach provides a clear framework for evaluating maternal tachycardia.
  • Effective management hinges on identifying the underlying cause promptly.
  • This structured assessment supports high-quality care for postpartum women with tachycardia.
