ECG Interpretation - AV Nodal Re-entrant Tachycardia

http://www.acadoodle.com The combination of an unfortunately timed atrial ectopic and the existence of two strands of conducting tissue with opposite electrical properties in the junctional region of the heart can establish a rapidly discharging, self sustaining, re-entrant loop of depolarising current. This current will be discharged distally into the ventricles and also in a retrograde fashion into the atria. This is the mechanism underlying a common paroxysmal supraventricular tachycardia (SVT); AVNRT. We will explain the mechanism underlying AVNRT in this video. Understanding the underlying mechanism generating this tachycardia will help you identify this common arrhythmia on the ECG.

ECG Interpretation - ECG Lead Perspectives

http://www.acadoodle.com The different leads of the ECG examine cardiac electrical activity from different perspectives. In this video we teach you the perspectives of the 12 ECG leads on cardiac depolarosiation and repolarisation. We consider the 12 leads in two groups of six, with the six chest leads (V1-V6, also referred to as the precordial leads) examining the flow of cardiac depolarisation and repolarisation in the horizontal plan and a second group of six leads (the standard leads and augmented leads) which examine these events in the vertical plane. For the experienced practitioner, looking at different areas on the ECG readout is like looking at different anatomical regions of the heart. Also, understanding the lead perspectives is crucial in the interpretation of cardiac arrhythmias.

Cardiac conduction system and its relationship with ECG

The heart's conductions system controls the generation and propagation of electric signals or action potentials causing the hearts muscles to contract and the heart to pump blood.

Anaesthesia UK : Anatomy relevant to epidural and subarachnoid blockade

The typical thoracic vertebra has a heart-shaped body (Figure 1) bearing one or two facets for articulation with the head of a rib. Its vertebral foramen is smaller and more circular than those of the cervical and lumbar regions. The two pedicles bear long and strong transverse processes. It articulates with its neighbouring vertebra with articular processes that bear nearly vertical facets facing (superior) posteriorly and (inferior) anteriorly. Its spinous process is long and slopes posteroinferiorly so that its tip overlies the level of the vertebral body below. Figure 1The typical lumbar vertebra has a larger kidney-shaped body and its vertebral foramen is larger than that of the thoracic vertebra (Figure 2). Its transverse processes are long and slender and its articular processes are directed (superior) posteromedially and (inferior) anterolaterally. Its spinous process is shorter, broader and more horizontal than those of the thoracic vertebrae.Figure 2Joints and ligaments of the vertebraeJoints: the articular surfaces of the bodies of adjacent vertebrae are covered by hyaline cartilage and united by a thick fibrocartilaginous intervertebral disc. These are strong cartilaginous joints designed for weight-bearing. The disc is a shock absorber, its centre, the nucleus pulposus, is gelatinous and surrounded by a fibrous part, the annulus fibrosus. Adjacent vertebrae articulate by two synovial facet joints between the paired articular processes.

Cardiology - Wikipedia, the free encyclopedia

Cardiology (from Greek καρδίᾱ kardiā, "heart" and -λογία -logia, "study") is a branch of medicine dealing with disorders of the heart. The field includes medical diagnosis and treatment of congenital heart defects, coronary artery disease, heart failure, valvular heart disease and electrophysiology. Physicians who specialize in this field of medicine are called cardiologists, a specialty of internal medicine. Pediatric cardiologists are pediatricians who specialize in cardiology. Physicians who specialize in cardiac surgery are called cardiothoracic surgeons or cardiac surgeons, a specialty of general surgery.

Autosomal dominant polycystic kidney disease (ADPKD)

ADPKD is an autosomal dominant disorder characterised by the presence of cysts in both kidneys. The cysts are numerous and fluid-filled, resulting in massive enlargement of the kidneys, often with progression to renal failure. The disease can also affect the liver, pancreas, and rarely, the heart and brain.  ADPKD has an incidence of 1/1000 and account for approximately 5% of patients with ESRF requiring replacement therapy.

Infective Endocarditis

This is a condition caused by infection of the endocardium by bacteria, or rarely, fungus. It most commonly affects the heart valves (natural or prosthetic), but can occur anywhere along the lining of the heart or blood vessels. It will most commonly occur at sites of previous damage, however, particularly virulent organisms (such as staphylococcus aureus and streptococcus pneumoniae) can infect previously normal areas of tissue; for example, Staph. Aureus will commonly infect the tricuspid valve in IV drug users.
