Mobile phone technology is continuously advancing- the smartphone allows users instant access to information via the internet. Downloadable applications (apps) are becoming widespread across medical specialities. The aim of this study was to assess the use of smartphone apps among urology trainees in Ireland.An anonymous electronic survey was distributed via Survey Monkey® to all urology trainees...
Continuous wound infiltration (CWI), i.v. patient-controlled analgesia (i.v.-PCA), and epidural analgesia (EDA) are analgesic techniques commonly used for pain relief after open abdominal surgery. The aim of this study was to evaluate the cost-effectiveness of these techniques. A decision analytic model was developed, including values retrieved from clinical trials and from an observational prospective...
Even though an analogue high-pass single pole filter with 0.05 Hz cut-off has been used for decades to define the low frequency response of electrocardiographs, in recent years the requirements for diagnostic quality ECG recordings have been expressed in terms of the system magnitude characteristic and its response to a rectangular pulse. The objective of this work is to design an analogue high-pass...
This paper presents a novel approach for designing the front-end of instrumentation amplifiers for use in dry electrode recording of the human electrocardiogram (ECG). The method relies on information provided by the characterization of the skin-electrode interface and the analysis of low frequency ECG criteria defined by international standards. Marginal measurements of capacitive elements of the...
This paper reports the design and development of a precision ECG signal generator intended for use in test and calibration of electrocardiographic equipment, ECG signal processing systems and as a cardiac teaching tool. It generates a Lead II signal which maintains the timing and profile characteristics of a Lead II electrocardiograph signal across a range of heart rates between 45 and 185 bpm in...
This paper reports the measurement of the properties of dry or pasteless conductive electrodes to be used for long-term recording of the human electrocardiogram (ECG). Knowledge of these properties is essential for the correct design of the input stage of associated recording amplifiers. Measurements were made on three commercially available conductive carbon based electrodes at pressures of 5mmHg...
