Pulse rhythm01:30

Pulse rhythm

1.3K
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...

Holter Monitor: 24-Hour Monitoring

1.9K
Holter monitoring is a continuous electrocardiography (ECG) recording that tracks the heart's electrical activity over an extended period, generally 24 to 48 hours. This noninvasive diagnostic tool detects irregular heart rhythms that may not be captured during a standard ECG performed in a clinical setting.DeviceThe Holter monitor is a portable, small device connected to several electrodes on the patient's chest. These electrodes detect the heart's electrical signals and transmit them to the...

Electrocardiogram

5.3K
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...

Dysrhythmias V: Evaluating Dysrhythmias

315
Dysrhythmias, also known as arrhythmias, are disturbances in the heart's rhythm that range from benign to life-threatening. A thorough evaluation is crucial for appropriate management and involves a comprehensive medical history, physical examination, and various diagnostic tests.Medical HistorySymptoms: Collect detailed information on palpitations, dizziness, syncope, chest pain, and fatigue. Note their onset, frequency, and triggers.Previous Cardiac Issues: Document any history of heart...

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

445
Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...

Electrocardiogram Fundamentals

1.4K
Introduction
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
Parts of an ECG
An ECG utilizes electrodes on the skin...

Area of Science:

  • Cardiology
  • Neurology
  • Medical Devices

Background:

  • Cardiac arrhythmias are frequent after ischemic stroke, increasing the risk of complications like recurrent strokes.
  • Early detection of these arrhythmias is crucial for effective patient management and risk reduction.

Purpose of the Study:

  • To evaluate the efficacy of a portable electrocardiography (ECG) patch in detecting arrhythmias in post-stroke patients.
  • To assess the role of continuous ECG monitoring in guiding treatment decisions for stroke patients.

Main Methods:

  • A prospective observational case series involving 10 adult patients in a hospital's neurology ward.
  • Continuous monitoring using portable ECG patches for up to 80 hours, following a baseline smartphone-based ECG.
  • Validation of detected arrhythmias by a cardiologist.

Main Results:

  • Portable ECG patches identified transient and potentially lethal arrhythmias, including atrial fibrillation and ventricular tachycardia, missed by the initial smartphone-based ECG.
  • Real-time data transmission enabled timely clinical interventions, improving patient management and outcomes.

Conclusions:

  • Continuous ECG monitoring with portable patches is superior to single-point smartphone ECG for detecting intermittent arrhythmias in stroke patients.
  • Incorporating portable ECG patches into post-stroke care facilitates early diagnosis, risk reduction, and enhanced therapeutic decision-making.
