Increased pulse rate01:17

Increased pulse rate

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 VII: Nursing Management of Dysrhythmias

Nursing management of dysrhythmias involves the following:AssessmentSubjective Assessment:The initial step involves gathering patient-reported symptoms such as dizziness, palpitations, and chest discomfort. It is crucial to collect a detailed history, including previous heart conditions, current medication use, and lifestyle factors like caffeine and alcohol consumption.Objective Assessment:This involves observing clinical signs such as jugular venous distention, cool and pale skin, and...

Dysrhythmias II: Classification of Tachyarrhythmias

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...
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 bradycardia...

Cardiac Catheterization IV: Nursing Management

Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...

Cardiomyopathy VI: Nursing Management

Assessment: Nursing management of patients with cardiomyopathy begins with a thorough assessment of the patient's history, including a family history of cardiomyopathy or sudden cardiac death, personal history of heart disease, hypertension, diabetes, and any alcohol consumption or drug use.During the physical examination, assess vital signs, look for signs of heart failure (such as edema, jugular venous distention, and cyanosis), auscultate for abnormal heart sounds (like murmurs and gallops),...

Area of Science:

  • Cardiology
  • Neurology
  • Autonomic Dysfunction

Background:

  • Postural tachycardia syndrome (POTS) is a prevalent condition often encountered in general practice.
  • Understanding the pathophysiology, including low effective circulating volume and decreased cerebral blood flow, is crucial.

Purpose of the Study:

  • To provide guidance for general neurologists, advanced practice providers, and general practitioners.
  • To aid in the diagnosis and treatment of POTS and related dysautonomias.

Main Methods:

  • Clinical experience of authors.
  • Nonsystematic literature review.
  • Expert opinion from the American Autonomic Society Education Committee.

Main Results:

  • POTS diagnosis is achievable in primary care settings using syndromic criteria: chronic orthostatic intolerance, excessive orthostatic tachycardia, absence of orthostatic hypotension, and exclusion of other causes.
  • First-line management involves education, salt, water, and exercise.
  • Pharmacological options include propranolol and midodrine.
  • Common comorbidities like migraine and neurocardiogenic syncope require screening and treatment.

Conclusions:

  • POTS and related conditions are common and manageable in primary care.
  • Initial diagnosis and treatment can be initiated by general practitioners.
  • Referral to specialists is recommended for refractory cases or diagnostic uncertainty.
