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.

Approach to Supraventricular Tachycardia - SVT

  I would like to share with you about SVTs, or supraventricular tachycardia, today. I'll be focusing on the pathophysiology, ECG features, and the management of SVT today. So this is a brief outline of the lecture today. I will be going through the definition of SVTs, followed by a brief classification of tachyarrhythmias, the pathophysiology behind it all, ECG features, and management principles of SVTs. I will round off the lecture with a clinical scenario related to the topic. This lecture is meant to be a basic introduction to SVTs, and is by all means not exhaustive. So without further ado, let us begin. Supraventricular tachycardias are defined as narrow complex tachycardias where the point of stimulation arises from above the bundle branches. There are many types of SVTs, as will be shown in the next slide, and some are more common than the others.   However, in our local context, it is used interchangeably with proximal supraventricular tachycardias, which make up a...

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 ...
