Electroconvulsive Therapy01:30

Electroconvulsive Therapy

Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early years,...

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

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...
Electrocardiogram01:29

Electrocardiogram

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 the T...

Electrocardiogram Fundamentals

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 to...

Area of Science:

  • Cardiology
  • Neurology
  • Biomedical Engineering

Background:

  • Electrocardiography (ECG) is crucial for monitoring cardiac activity.
  • ECG artifacts, or unwanted signals, can arise from various sources, including patient motion and medical devices.
  • Artifacts can mimic or obscure true cardiac events, complicating diagnosis and treatment.

Observation:

  • Electroconvulsive therapy (ECT) involves electrical stimulation and can potentially cause physiological changes.
  • The literature lacks reports on ECG artifacts specifically occurring during ECT.
  • This study observed ECG artifacts in a patient undergoing ECT.

Findings:

  • Two distinct mechanisms causing ECG artifacts were identified in the same patient during ECT.
  • These artifacts were not previously described in the context of electroconvulsive therapy.
  • The specific nature of these two artifact mechanisms provides new insights into signal interference during ECT.

Implications:

  • Understanding these ECT-specific ECG artifacts is vital for accurate cardiac monitoring during the procedure.
  • This knowledge can help clinicians differentiate true cardiac events from artifactual signals.
  • Further research into artifact reduction techniques during ECT may improve patient safety and data quality.
