- Noninvasive electrocardiographic imaging for cardiac electrophysiology and arrhythmia. Ramanathan, Charulatha; Ghanem, Raja N.; Jia, Ping; Ryu, Kyungmoo; Rudy, Yoram // Nature Medicine;Apr2004, Vol. 10 Issue 4, p422
Over 7 million people worldwide die annually from erratic heart rhythms (cardiac arrhythmias), and many more are disabled. Yet there is no imaging modality to identify patients at risk, provide accurate diagnosis and guide therapy. Standard diagnostic techniques such as the electrocardiogram...
- Characteristic wave detection in ECG signal using morphological transform. Sun, Yan; Chan, Kap Luk; Krishnan, Shankar Muthu // BMC Cardiovascular Disorders;2005, Vol. 5, p28
Background: Detection of characteristic waves, such as QRS complex, P wave and T wave, is one of the essential tasks in the cardiovascular arrhythmia recognition from Electrocardiogram (ECG). Methods: A multiscale morphological derivative (MMD) transform-based singularity detector, is developed...
- Taking ECGs: being skilled, competent and confident. Peate, Ian; Wild, Karen // British Journal of Healthcare Assistants;Jul2012, Vol. 6 Issue 7, p328
The phrase 'cardiac monitoring' usually refers to either continuous or one-off electrocardiograph (ECG). There are many ways of monitoring cardiac function, for example, telemetry (this allows cardiac monitoring to be done at a distance) and haemodynamic monitoring (monitors the pressure and...
