Advancements in technology have enhanced the performance of pacemakers but made the interaction between the pacemaker and the heart becoming increasingly complex, and its is difficult to interpret the paced ECGs (PGCGs). This paper introduces a brief method to interpret PECGs, which illustrate the timing intervals graphically and avoid using symbols and strings.

A 75-year-old male patient had stable angina pectoris After coronary angiography we decided to perform a coronary artery bypass graft surgery. Twenty years ago the patient underwent radical cystectomy and bilateral ureterosigmoidostomy because of bladder cancer After that, his micturition was via the rectum. We did not experience that before. As is known, monitoring of urine output is very important after cardiac surgery The patient was consulted with an urologist for how to monitor urine output in him. Transrectal catheterization was recommended for our follow-up, but before the catheterization bowel cleansing is necessary. Four-vessel on-pump coronary artery bypass graft surgery was performed without any problem. Peroperative urine volume and arterial blood gas results were normal. Urine output is a sensitive variable reflecting the patient's effective blood volume and tissue perfusion. Urinary catheterization is a standard for all cardiac surgeries and it allows the patients' urine to drain freely from the bladder for collection. Monitoring of urine output in patients with ureterosigmoidostomy is impossible by standard urinary catheterization method. In this casewe performed transrectal catheterization for Urine flow follow-up. Urine flow follow-up is essential after the open-heart surgery and it can be measured in different ways, as in our case.

AIM: To validate the feasibility of digital tomosynthesis of the abdomen(DTA) combined with contrast enhanced ultrasound(CEUS) in assessing complications after endovascular aortic aneurysm repair(EVAR) by using computed tomography angiography(CTA) as the gold ***: For this prospective study we enrolled 163 patients(123 men; mean age, 65.7 years) referred for CTA for EVAR follow-up. CTA, DTA and CEUS were performed at 1 and 12 mo in all patients, with a maximum time interval of 2 ***: Among 163 patients 33 presented complications at CTA. DTA and CTA correlated for the presence of complications in 32/33(96.96%) patients and for the absence of complications in 127/130(97.69%) patients; the sensitivity, specificity, positive predictive value(PPV), negative predictive value(NPV) and accuracy of DTA were 97%, 98%, 91%, 99%, and 98%, respectively. CEUS and CTA correlated for the presence of complications in 19/33(57.57%) patients and for the absence of complications in 129/130(99.23%) patients; the sensitivity, specificity, PPV, NPV and accuracy of CEUS were 58%, 99%, 95%, 90%, and 91%, respectively. Sensitivity, specificity and accuracy of combining DTA and CEUS together in detecting EVAR complications were 77%, 98% and 95%, ***: Combining DTA and CEUS in EVAR follow-up has the potential to limit the use of CTA only in doubtful cases.
