Glasgow ECG Interpretation Algorithm

ECG Interpretation Algorithms

Ever since a ECG machine was developed, there have been a number of modifications and advancements that has helped technology evolve. In 1970s,  initial attempts at developing  the first ECG interpretation algorithm were put in. Since the accuracy of those algorithms were not up to the mark, several databases were built by various institutions to 9compare ECGs and check for accuracy. The methods for interpretation might include not limited to:

  1. Time-frequency methods
  2. Neural networks
  3. Comparison with templates

ECG – Electrocardiographs

Did you know that ECG as a concept originated in 1901? They coined a term Electrocardiograph as Electro meant Electrical Activity, Kardio meant Heart and Graph meant to write. Briefly put, a ECG measures the electrical activity of the heart and traces it as a graph helping the physician understand how your heart works. From then (machines with analog electronics), to now(with analog-to-digital converters), Electrocardiographs have evolved and come a long way.

A deep dive into BPL-Alpinion’s Intra-oral transducer

IO3-12, the latest innovation in the field of Ultrasonography is BPL-Alpinion’s sophisticated intra-oral transducer. Designed with a footprint as small as the size of a toothbrush, the transducer performs trans-oral sonography with ease. With its small footprint and easy grip, clinicians can easily manoeuvre and view intra- oral structures such as salivary duct dilatations and can also check the position of stone real time during Sialo lithotomy.

Automated External Defibrillator – A must have in all public places

“A stitch in time saves nine” says an adage and when it comes to last minute efforts in saving lives, every second counts. Public access defibrillators (PAD) or Automated External Defibrillators (AED) as they are called, are defibrillators used to revive a person of cardiac arrest. These devices come with automated voice controls and easy operations for everyone to be able to use it in times of need.

Transducers and Single Crystal Technology

Performance of any ultrasound machine depends critically on the transducer but transducer performance has been one of the bottlenecks that prevents the end users from reaching their theoretical resolution limit specially when the goal is to differentiate between healthy and diseased tissue, without going for any invasive procedure. Knowledge is required from a variety of disciplines such as acoustics and vibration, electrical engineering, material science, medical imaging, anatomy and physiology.
