We report the case of an 86-year-old man referred for abdominal pain and ECG signs of inferior myocardial infarction. Transthoracic, transoesophageal and contrast echocardiographs showed a septal intra-mural haematoma, dissecting the right ventricle wall and partially obliterating the right ventricle lumen. A patent communication with left ventricle with extensive wall thrombosis was present at...

Background Despite increasing application of non-contrast techniques Fresh Blood Imaging (FBI) and Quiescent Inflow Single-Shot (QISS) in the evaluation of peripheral arterial disease (PAD), imaging of abdominal/pelvic station remains a challenge. B0 and B1 inhomogeneity, motion artefacts and poor ECG trigger may diminish the image quality and reduce the diagnostic performance. In this study, w...

Prolonged monitoring by cardiac electrocardiogram (ECG) sensors is useful for patients with emergency heart conditions. However, implant monitoring systems are limited by lack of tissue biocompatibility. Here, we developed an implantable ECG sensor for real-time monitoring of ventricular fibrillation and evaluated its biocompatibility using an animal model. The implantable sensor comprised tran...

There is a need for affordable, widely deployable maternal-fetal ECG monitors to improve maternal and fetal health during pregnancy and delivery. Based on the diffusion-based channel selection, here we present the mathematical formalism and clinical validation of an algorithm capable of accurate separation of maternal and fetal ECG from a two channel signal acquired over maternal abdomen. The p...

Fetal Electrocardiogram Extraction (FECG) identifies the congenital heart problems at the earlier stage. The major problem in the non invasive procedure is the extraction of FECG from Maternal ECG (MECG) and many interferences. The proposed methods (i) Combination of Adaptive Neuro Fuzzy Inference (ANFIS) and Fractional spline wavelet (ii) Combination of Fractional spline wavelet and ANFIS (iii...

AIMS Phrenic nerve palsy (PNP) is still a cause for concern in Cryoballoon ablation (CBA) procedures. New surveillance techniques, such as invasive registration of the compound motor action potential (CMAP), have been thought to prevent the occurrence of PNP. The present study investigates the impact of CMAP surveillance via an alternative and non-invasive ECG-conduction technique during CBA. ...

OBJECTIVES The purpose of this study was to estimate the value of preoperative electrocardiographic (ECG) monitoring in predicting postoperative cardiac events in patients undergoing abdominal aortic surgery. DESIGN A prospective open study. SETTING University Hospital. MATERIALS One hundred consecutive patients were studied before aortic or aortofemoral surgery by ambulatory ECG monitori...
