Electrocardiogram01:29

Electrocardiogram

7.8K
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...

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations01:19

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

727
The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

Pericarditis II: Clinical Features and Diagnostic Tests

538
Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...

Acute Coronary Syndrome III: Diagnostic Studies

426
Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

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

957
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...

Myocarditis II: Clinical Features and Diagnostic Tests

445
Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...

Summary

Electrocardiogram (ECG) abnormalities are common in patients with cholecystitis and cholangitis. These changes, often T-wave abnormalities, are linked to disease severity and electrolyte imbalances, resolving with biliary disease treatment.

Area of Science:

  • Cardiology
  • Gastroenterology
  • Internal Medicine

Background:

  • Electrocardiographic (ECG) changes in biliary diseases like cholecystitis and cholangitis are infrequently documented.
  • Detailed observational data on ECG abnormalities in these conditions are scarce.

Purpose of the Study:

  • To determine the prevalence and characteristics of ECG abnormalities in patients with cholecystitis and cholangitis.
  • To identify clinical factors associated with ECG changes in biliary disease.

Main Methods:

  • Retrospective analysis of 402 hospitalized patients with biliary diseases.
  • Included 79 cholecystitis and 111 cholangitis cases after exclusions.
  • Evaluated ECG changes (T-wave, ST-segment, conduction blocks) and clinical variables.

Main Results:

  • ECG abnormalities found in 43% of cholecystitis and 34% of cholangitis cases.
  • T-wave abnormalities were most frequent, followed by ST-segment changes and conduction blocks.
  • Associated factors included low potassium and high severity in cholecystitis; stroke history and high ALP in cholangitis.

Conclusions:

  • Significant ECG abnormalities occur in patients with cholecystitis or cholangitis.
  • Awareness is crucial for avoiding misdiagnosis and ensuring proper management.
  • ECG changes normalized after treating the underlying biliary disease.
