Pulse rhythm01:30

Pulse rhythm

797
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...

Electrocardiogram Fundamentals

594
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:

  • Emergency Medicine
  • Cardiology
  • Critical Care

Background:

  • Transvenous pacemaker placement is a core skill in emergency medicine for managing severe dysrhythmias.
  • Temporary cardiac pacing is a life-saving intervention for various cardiac conditions.

Approach:

  • This narrative review focuses on transvenous pacemaker placement specifically within the emergency department.
  • Optimal insertion sites include the right internal jugular and left subclavian veins.
  • Ultrasound guidance can enhance lead placement accuracy using subxiphoid approaches.

Key Points:

  • Indications include symptomatic bradycardia, unstable tachydysrhythmias like torsades de pointes, and failed transcutaneous pacing.
  • Successful placement involves advancing a pacing wire with a balloon until electromechanical capture is achieved in the right ventricle.
  • Troubleshooting mechanical capture failure requires evaluating equipment and potential malfunctions.

Conclusions:

  • A thorough understanding of transvenous pacemaker placement is essential for emergency clinicians.
  • Proper technique and awareness of potential complications are crucial for patient safety.
