Increased pulse rate01:17

Increased pulse rate

1.6K
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...

Decreased pulse rate

1.0K
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...

Pulse rhythm01:30

Pulse rhythm

1.7K
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...

Exercise Stress Test01:26

Exercise Stress Test

2.3K
Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

Dysrhythmias III: Characteristics of Dysrhythmias01:29

Dysrhythmias III: Characteristics of Dysrhythmias

709
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...

Heart Failure VII: Nursing Interventions

787
The first step in nursing management of a patient with heart failure involves thoroughly assessing the patient's medical history.Subjective Data: Obtain the patient's medical history of coronary artery disease, hypertension, myocardial infarction, and symptoms like dyspnea, orthopnea, and paroxysmal nocturnal dyspnea.Objective Data: Conduct a physical examination to identify findings such as jugular vein distention, pulmonary crackles, tachycardia, murmurs, peripheral edema, and vital signs,...

Summary

Repetitive task practice in stroke rehabilitation can increase aerobic intensity. Incorporating gross motor tasks in a standing position with targets at or above shoulder height maximizes this response.

Area of Science:

  • Neurology
  • Exercise Physiology
  • Rehabilitation Science

Background:

  • Cardiopulmonary benefits of aerobic exercise poststroke are established.
  • Typical stroke rehabilitation lacks sufficient aerobic response.

Purpose of the Study:

  • Characterize heart rate response during upper extremity repetitive task practice (RTP).
  • Identify factors predicting higher aerobic intensity during RTP.

Main Methods:

  • Secondary analysis of data from a randomized clinical trial.
  • 19 participants with chronic stroke.
  • 90 minutes of RTP for 24 sessions over 8 weeks.
  • Aerobic intensity measured by heart rate reserve (HRR).

Main Results:

  • 79.5% of tasks elicited very light aerobic response (<30% HRR).
  • 10.3% of tasks elicited moderate to vigorous aerobic response (≥40% HRR).
  • Standing position, gross motor tasks, and targets at or above shoulder height predicted higher HRR (p < .001).

Conclusions:

  • To maximize aerobic intensity during poststroke RTP, therapists should incorporate gross motor tasks in a standing position with targets at or above shoulder height.
  • Monitoring heart rate can enhance awareness of aerobic response during training.
