ECG

My interest in the field of Electrocardiography started with my high school biology research assignment, which involved taking limb lead ECG's of classmates and investigating time interval between the QRS complex and the pulse wave measured from a pulse oximeter. Since then I was involved with various research projects, including:

Spatial ECG parameters for risk stratification

• Abnormal QRS-T angle predicts mortality in patients with suspected coronary disease

Pre-hospital transmission of ECG's

High frequency ECG analysis for the detection of ischemia during stress testing

ECG standards and technical solutions

• • a toolkit to convert ECG's from different manufacturer formats

Visualisation of the ECG

• • an initiative to process and visualize the body surface potential map
