Patient access to reperfusion therapy and the use of primary percutaneous coronary intervention (p-PCI) or thrombolysis (TL) varies considerably between European countries. The aim this study was obtain a realistic contemporary picture how patients with ST elevation myocardial infarction (STEMI) are treated in different chairpersons national working groups/societies interventional cardiology countries selected experts known be involved registries joined writing group upon invitation. Data...
Patients with frequent episodes of paroxysmal atrial fibrillation (AF) are prone to develop permanent AF and have an increased thromboembolic risk. We previously shown that P wave dispersion (P dispersion), defined as the difference between maximum minimum duration, duration maximum) can distinguish patients lone AF. The ability those ECG markers other clinical variables detect at risk for recurrent was tested in 88 patients, aged 64 +/- 12 years. All had a history symptomatic during last 2...
The aim of this article is to present a survey on applications Pneumatic Artificial Muscles (PAMs). PAMs are highly non-linear pneumatic actuators where their elongation proportional the interval pressure. During last decade, there has been significant increase in industrial and scientific utilization due advantages such as high strength small weight, while various types with different technical characteristics have appeared relative literature. This will summarize key enabling that focusing...
In this paper, the positioning control problem of pneumatic muscle actuators (PMAs) is being considered. A two-degree-of-freedom nonlinear proportional-integral-derivative structure synthesized, providing ameliorated compensation PMAs' hysteretic phenomena and advanced robustness through disturbance cancellation. Experimental studies are utilized to prove overall efficiency proposed scheme with regard set-point tracking performance for position a single PMA, torsion angle nonsymmetrical...
The CRYO4PERSISTENT AF (Cryoballoon Ablation for Early Persistent Atrial Fibrillation) trial aims to report long-term outcomes after a single pulmonary vein isolation (PVI)–only ablation procedure using the second-generation cryoballoon in persistent atrial fibrillation (PerAF) patients. Pulmonary is recognized as cornerstone of (AF) ablation, including PerAF. (NCT02213731) prospective, multicenter, single-arm designed assess single-procedure PVI cryoballoon. primary endpoint was freedom...
Aims Habitual cigarette smokers, paradoxically, present improved short-term prognosis after acute myocardial infarction, a phenomenon often termed 'smoker's paradox'. We sought to examine smokers' post-infarction survival advantage in countrywide survey of unselected, consecutive patients presenting with infarction.
In this paper, the modeling and control problem of a pneumatic artificial muscle (PAM) is being considered. The PAM an actuator characterized by decrease in actuating length when pressurized. Its nonlinear nature time-varying parameters cause difficulties their characteristics, as well designing controllers for high-performance positioning systems. A constrained linear piecewise affine system model approximation formulated, scheme composed following synthesized: 1) feedforward term...
Quadruped robots have the advantages of traversing complex terrains that are difficult for wheeled robots. Most reported quadruped built by rigid parts. This paper proposes a new design using soft actuators driven tendons as four legs. Compared to robots, proposed robot has inherent safety, less weight and simpler mechanism fabrication control, but corresponding challenge is accurate mathematical model applicable model-based control derive dynamics. To synthesize optimal gait controller...
P wave dispersion (P dispersion), defined as the difference between maximum and minimum duration, duration maximum) are electrocardiographic (ECG) markers that have been used to evaluate discontinuous propagation of sinus impulses prolongation atrial conduction time, respectively. To study effects myocardial ischemia on maximum, 95 patients with coronary artery disease (CAD) typical angina pectoris 15 controls anginalike symptoms underwent 12‐lead surface ECG during after relief pain. During...
Exercise electrocardiography is an imperfect test for the detection of coronary artery disease. We attempted to improve diagnostic accuracy exercise testing as a noninvasive method disease by using combination left and right precordial leads.
We hypothesized that the variance of P wave duration (P variance) in 12‐lead ECG could reflect spatial dispersion due to inhomogeneous and delayed propagation sinus impulses atria, moreover present better reproducibility than maximum have already been used for prediction idiopathic paroxysmal AF, also tested a semiautomated PC‐based method improve accuracy measurements. A was obtained from 60 patients with AF 50 healthy controls. All ECGs were analyzed manually using magnifying lens...
The aim of this article is to provide a survey on the most popular modeling approaches for Pneumatic Muscle Actuators (PMAs). PMAs are highly non-linear pneumatic actuators where their elongation proportional interval pressure. During last decade, there has been an increase in industrial and scientific utilization PMAs, due advantages such as high strength small weight, while various types with different technical characteristics have appeared literature. This will: a) analyze PMA's...
The aim of this article is to present a survey on inspection applications Pneumatic Wall-Climbing Robots (PWCR). In general, PWCR utilizes negative pressure as its adhesion method, through mainly suction cups or thrust-based mechanisms. Their main advantage being their ability climb non-ferromagnetic surfaces, such glass and composite materials, in comparison with climbing robots based magnetic methods. A growing application area the utilization PWCRs for purposes accelerating otherwise time...
Right phrenic nerve (PN) injury is a major complication of thermal ablation atrial tachycardias (ATs) originated from the superior vena cava (SVC). We report case 41-year-old female patient admitted for catheter frequent paroxysmal AT resistant to antiarrhythmic drugs. Electroanatomical activation map demonstrated focal origin located at lateral aspect SVC, ∼17 mm above breakthrough sinus node wavefront. Importantly, high-output pacing this site resulted in PN capture. To avoid injury,...
Objective and methods To determine whether hypertensive patients at risk for paroxysmal atrial fibrillation (AF) could be detected while in sinus rhythm, a computer-based 12-lead surface electrocardiogram was recorded 50 with history of AF (group A) 60 without B). The maximum P-wave duration (Pmaximum), the minimum (Pminimum), dispersion (Pdispersion = Pmaximum − Pminimum), adjusted (APdispersion Pdispersion/square root number measurable leads), mean (mean P) standard deviation all measured...
