Pulse rhythm01:30

Pulse rhythm

771
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...

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...

Electrocardiogram01:29

Electrocardiogram

2.2K
An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.
Three major waveforms are present in a typical ECG recording: the P wave, the QRS complex, and...

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...

Equipments Used To Measure Blood Pressure

846
Direct Method
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

Pulse01:16

Pulse

473
When the heart pumps blood out, arterial elastic fibers play a crucial role in sustaining a high-pressure gradient. They expand to accommodate the received blood and then recoil - a process known as the pulse that can be either manually palpated or electronically quantified. Despite a reduction in its effect with increased distance from the heart, elements of the pulse's systolic and diastolic components persist, observable even at the arteriole level.
The pulse serves as a clinical...

Area of Science:

  • Cardiology
  • Internal Medicine

Background:

  • Palpitations are frequently reported symptoms with low mortality but can significantly impair quality of life and increase healthcare utilization.
  • Common triggers include cardiac, endocrine, metabolic, medication-related, or psychosomatic disorders.

Purpose of the Study:

  • To provide a comprehensive overview of the evaluation and management of palpitations.
  • To discuss diagnostic approaches and treatment strategies for various causes of palpitations.

Main Methods:

  • Review of current literature and clinical guidelines for diagnosing and managing palpitations.
  • Emphasis on detailed patient history, physical examination, laboratory studies, and electrocardiography (ECG).
  • Discussion of advanced diagnostic tools such as echocardiography, stress testing, and electrophysiologic studies.

Main Results:

  • A thorough history, physical exam, and ECG are often sufficient for diagnosis.
  • Further testing is indicated to rule out cardiac arrhythmia, structural, or ischemic heart disease.
  • Management varies from reassurance and trigger avoidance to atrioventricular nodal blockers or cardiac ablation for tachyarrhythmias.

Conclusions:

  • Palpitations require a systematic diagnostic approach to identify the underlying etiology.
  • Management should be individualized based on the suspected cause, ranging from conservative measures to invasive procedures.
  • Wearable devices show promise for arrhythmia detection and patient engagement in healthcare.
