TPM Settings: How to check Stimulation & Sensitivity Threshold of Temporary Pacemaker

Temporary Pacemaker Settings
Usual TPM (Temporary Pacemaker) Showing Dials and Indicators

Stimulation Threshold Testing:

  1. Set Rate at least 10 beats above patient's intrinsic rate
  2. Decrease Output by slowly turning output dial counterclockwise until ECG shows loss of capture.
  3. Increase Output by slowly turning output dial clockwise until ECG shows consistent capture. This value is the Stimulation Threshold 
  4. Set Output to 2 to 3 times higher than the Stimulation Threshold (Safety Margin)
  5. Restore Rate to previous value.


Sensing Threshold Testing:

  1. Set Rate at least 10 beats below the patient's intrinsic rate.
  2. Set Output to 0.1 mA
  3. Decrease Sensitivity by slowly turning Sensitivity dial counterclockwise until pace indicator flashes continuously.
  4. Increase Sensitivity by slowly turning Sensitivity dial clockwise until sense indicator flashes and pace indicator stops flashing. This value is the Sensing Threshold.
  5. Set Sensitivity to Half of the threshold value (Safety Margin)
  6. Restore Rate and Output to previous values.

STEMI ECG Criteria and Universal Definition of MI

  STEMI ECG Criteria and the Universal Definition of Myocardial Infarction: A Complete Guide for Clinicians Early and accurate diagnosis of acute myocardial infarction (AMI) remains the cornerstone of reducing morbidity and mortality in patients presenting with chest pain. Among all forms of acute coronary syndromes (ACS), ST-elevation myocardial infarction (STEMI) represents the most time-sensitive emergency, requiring immediate reperfusion therapy. This article provides a clinically relevant summary of the STEMI ECG criteria and the Universal Definition of Myocardial Infarction (UDMI), based on the latest consensus guidelines from the ESC, ACC, AHA, and WHF. --- 1. Understanding STEMI: Why Accurate ECG Interpretation Matters A 12-lead ECG remains the first and most critical diagnostic test when evaluating suspected myocardial infarction. STEMI is identified when there is evidence of acute coronary artery occlusion, producing transmural ischemia and characteristic ST-segment eleva...

Learn Echocardiography | Standard Protocol for Performing Comprehensive Echocardiogram | Explained with Images and Videos

  If you are just starting to learn echocardiography, you will find that learning the full echo examination protocol will be immensely useful. The full protocol will provide a solid foundation for your career in echo. I personally found that once I could execute the standard protocol flawlessly, I was able to add and refine additional echo scanning skills while deepening my understanding of the purpose of each echo image. The echo protocol illustrated in this article is the same one we currently use for all our patients in the hospital and meets or exceeds the standards of American Society of Echocardiography (ASE) for an adult echocardiography examination. The protocol presented here is meant as a guideline and does not cover every aspect (such as off axis views) of an echo examination. Also other hospitals will probably have slight variations of this protocol depending on the lab's needs, which is normal. This article's main purpose is to provide a solid foundation for ...

2025 AHA/ACC Hypertension Guidelines Key points

  2025 AHA/ACC Hypertension Guidelines Explained: A Clear Summary for Clinicians and Students Hypertension remains one of the most significant contributors to cardiovascular morbidity and mortality worldwide. With continual refinement of evidence and risk-based strategies, the 2025 AHA/ACC Hypertension Guidelines bring an updated, practical approach that clinicians can use in daily practice. To make learning easier, I’ve created a clean and modern infographic summarizing all major recommendations. You can download it below and use it for study, teaching, or clinical reference. Download Infographic (PNG): 2025 Hypertension Guideline Infographic This post breaks down the key points from the guidelines and complements the infographic for a complete understanding. --- BP Categories: Understanding the Updated Thresholds The guidelines maintain the well-established classification of blood pressure: Normal: <120 / <80 Elevated: 120–129 / <80 Stage 1 Hypertension: 130–139 and/or 8...
