Disturbances in Heart Rhythm01:29

Disturbances in Heart Rhythm

5.5K
Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow heart...

Imbalances in Cardiac Output01:26

Imbalances in Cardiac Output

3.3K
The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...

Introduction Cardiac Emergencies

569
Cardiac emergencies are critical situations involving the heart that require immediate medical intervention to prevent severe complications or death. These emergencies often arise from underlying heart conditions that impair the heart's ability to function correctly.Types of Cardiac EmergenciesThe most common types of cardiac emergencies include Acute Coronary Syndrome (ACS), myocardial infarction (MI), cardiac arrest, and heart failure.Acute Coronary Syndrome (ACS)Acute Coronary Syndrome (ACS)...

Cardiopulmonary Resuscitation I: Adult

1.3K
Cardiopulmonary resuscitation, or CPR, is a life-saving emergency procedure performed when a person's heart has stopped beating or they are no longer breathing. The foundation of CPR is Basic Life Support (BLS), which focuses on the early recognition of cardiac arrest, the immediate start of high-quality chest compressions, and the timely use of an automated external defibrillator (AED).Assessing Responsiveness and Checking the Carotid PulseWhen approaching an unresponsive person, first ensure...

Cardiopulmonary Resuscitation III: AED Use

1.7K
Introduction to AEDAn Automated External Defibrillator (AED) is a portable medical device that analyzes the heart's rhythm and, if necessary, delivers an electrical shock to help the heart re-establish an effective rhythm during sudden cardiac arrest (SCA). SCA occurs when the heart suddenly and unexpectedly stops beating, leading to a loss of blood flow to the brain and other vital organs. In such emergencies, time is of the essence, and using an AED, combined with Cardiopulmonary...

Cardiopulmonary Resuscitation IV: Pharmacological Management

1.7K
Pharmacologic intervention is crucial in treating cardiac arrest patients during ACLS or Advanced Cardiovascular Life Support. The ACLS algorithms guide the administration of specific drugs based on the patient's cardiac arrest rhythm, which includes pulseless ventricular tachycardia (VT), ventricular fibrillation (VF), asystole, and pulseless electrical activity (PEA).EpinephrineIndication: Epinephrine is the first-line drug for all cardiac arrest rhythms.Mechanism of Action: Epinephrine...

Area of Science:

  • Public Health
  • Epidemiology
  • Emergency Medicine

Background:

  • Cardiac arrest (CA) in educational settings is understudied.
  • School-based automated external defibrillators (AEDs) may improve outcomes.
  • Understanding CA epidemiology in schools is crucial for preparedness.

Purpose of the Study:

  • To enhance understanding of cardiac arrest epidemiology within schools.
  • To investigate the incidence and characteristics of school-based cardiac arrests.
  • To evaluate the role of school-based automated external defibrillators.

  • Retrospective analysis of emergency medical service-treated, out-of-hospital cardiac arrests in Seattle and King County schools (1990-2005).
  • Data sourced from cardiac arrest registries and incident report forms.
  • Identification of cases based on cardiac arrest location data.

Main Results:

  • 97 cardiac arrests occurred in schools, representing 0.4% of all treated CA and 2.6% of public location CA.
  • Incidence varied by school level: 1 CA per 8 colleges, 1 per 125 high schools, 1 per 200 lower-level schools.
  • Estimated annual incidence was 0.18/100,000 person-years for students and 4.51/100,000 person-years for faculty/staff.

Conclusions:

  • This study characterizes school-setting cardiac arrest.
  • Findings provide a framework for preparedness efforts and outcome expectations.
  • Highlights the need for targeted strategies for cardiac arrest management in educational institutions.
