Cardiac Physiology in Practice - Experienced Cardiac Physiologists - Mitchell Cowan

Mitchell Cowan

Electrophysiology, ECG & Cardiac Devices

Mitch formerly served as the Senior Cardiac Physiologist at Royal North Shore Hospital in Sydney, Australia, where he trained in Electrophysiology & Cardiac Devices. With a Graduate Diploma of Electrophysiology from CEPIA and certifications in Cardiac Electrophysiology and Cardiac Devices from IBHRE, he now sits on the CEPS exam writing committee for IBHRE. Mitchell also works with a 3D electroanatomical mapping company in a clinical role, performing EP procedures every day. 

Committed & passionate about contributing to the field of Electrophysiology, Mitch is an active participant in medical education and research. He frequently supports Medical Registrar training programs such as the HEART Course & CSANZ education days. He serves as a guest lecturer for the local health district, Professionals in Cardiac Science Australia, Western Sydney University and is a regular speaker at conferences, both nationally and internationally.

A frequent contributor to international conferences, he has presented on various EP topics, including differentiating AVJRT & Junctional Ectopic Tachycardia, the role of Epicardial structures in AF recurrence and Atrial Flutter, Ablating beyond the veins in Atrial Fibrillation, VT localization, and Substrate mapping in VT.

In addition to clinical work, he enjoys contributing to and leading various research projects. His current pet project involves a multicentre study validating a new algorithm called INDEX-WPW, aimed at predicting successful accessory pathway ablation sites based on ECG features. His research interests also include predicting the delayed occurrence of sudden death post-TAVI using perioperative EP & ECG features, and he has several other publications, including authoring chapters on Atrial Flutter, RVOT VT and ARVC in the “Cardiac Electrophysiology in Clinical Case Review” textbook.
Mitch remains deeply committed to education and research in Electrophysiology, continuously striving to empower healthcare professionals and improve the patient experience.

Cardiac Physiology in Practice - Experienced Cardiac Physiologists - Kenny Ng

Kenny Ng

ECG and Echocardiography

Kenny Ng was the Senior Cardiac Physiologist at Royal North Shore, before Mitch. He is committed and passionate about developing education for Echocardiography and Electrocardiography and is responsible for mentoring a number of Cardiac Physiologists and Registrars in Echocardiography. He also assists in the education of staff in the Cardiac Catheterisation Lab and has lectured in multiple national educational webinars and meetings.

He has just recently submitted an abstract for CSANZ alongside some colleagues. He works as a Lecturer at Western Sydney University in Echocardiography. His qualifications include a Graduate Diploma of Electrophysiology and a Graduate Diploma in Cardiac Ultrasound with QUT.

Cardiac Physiology in Practice - Experienced Cardiac Physiologists - Natasha Saad

Natasha Saad

ECG, cardiac devices and electrophysiology

A Senior Cardiac Physiologist and specialising in Cardiac Devices & Electrophysiology, Natasha has extensive experience in performing Electrophysiological procedures with over 10 years of experience in large tertiary centers in the UK and Australia. She has overhauled the cardiac devices program at Royal North Shore Hospital by developing and implementing extensive professional development and accreditation programs and inter-departmental communication frameworks.

She is currently the lead EP Cardiac Physiologist and Royal North Shore and is passionate about mentoring her physiologist and medical trainee colleagues in the EP lab. 

Her qualifications include a Graduate Diploma in Cardiac Electrophysiology, and a certificate in both Cardiac Electrophysiology and Cardiac Devices through IBHRE. She is currently conducting research into predicting latent arrhythmias post TAVI procedures using electrophysiological properties and measuring QT intervals in the context of bundle branch blocks. She is also an investigator for the multicentre INDEX-WPW study on predicting successful ablation sites for patients with WPW based on their ECG. She’s focused on raising professional standards of healthcare by implementing comprehensive educational programs in ECG, Devices and EP.
