Basic ECG Interpretation Our ECG Interpretation Training and Reference Guides provide basic lessons for ECG analysis as well as a quick reference guide for over 40 types of ECG tracings. The arrhythmia drills and quizzes allow you to practice ECG interpretation. What is ECG Interpretation? An electrocardiogram or ECG, records electrical activity in the heart. An ECG machine records these electrical signals across multiple heart beats and produces an ECG strip that is interpreted by a healthcare professional. How Electrocardiograms Work - ECG Strips To briefly summarize the components of a normal ECG tracings, it consist of waveform components which indicate electrical events during one heart beat. These waveforms are labeled P, Q, R, S, T and U. P wave is the first short upward movement of the ECG tracing. It indicates that the atria are contracting, pumping blood into the ventricles. The QRS complex, normally beginning with a downward deflection, Q; a larger upwards deflection, a peak (R); and then a downwards S wave. The QRS complex represents ventricular depolarization and contraction. The PR interval indicates the transit time for the electrical signal to travel from the sinus node to the ventricles. T wave is normally a modest upwards waveform representing ventricular repolarization. ECG Interpretation illustration spacer image ECG Training - Introduction The focus of this introductory ECG course is to provide a tutorial about the main features of ECGs along with a method for analyzing ECGs. This method includes assessment of rhythm, calculating heart rate, observing P-wave forms, measurement of intervals and segments and the evaluation of other relevant waves. ECG practice exercises serve to reinforce the lesson content.
Uterine polyps are growths attached to the inner wall of the uterus that extend into the uterine cavity. Overgrowth of cells in the lining of the uterus (endometrium) leads to the formation of uterine polyps, also known as endometrial polyps. These polyps are usually noncancerous (benign), although some can be cancerous or can eventually turn into cancer (precancerous polyps). Uterine polyps range in size from a few millimeters — no larger than a sesame seed — to several centimeters — golf-ball-size or larger. They attach to the uterine wall by a large base or a thin stalk.

Purpose The complication rate in patients treated with the Linton procedure was unacceptably high. SEPS is minimal invasive treatment modality for chronic venous insufficiency and venous ulcers. Materials and Methods252 limbs of 229 patients who underwent SEPS procedure and/or safenous vein ablati...on from May 2003 to January 2008. Tourniquet was not used and two-port technique was preferred for operation. Skin graft was not used. Honeysoft (medical honey) was used for wound care in selected cases. Results According to CEAP clinical Classification 112 limbs were class 6, 70 limbs (class 5), 70 limbs (Class4) respectively. Greater saphenous vein stripping and/or high ligation, and varicose vein excision accompanied SEPS in 241limbs who had combined Sapheno-femoral junction and perforator vein insufficiencyand SEPS was performed alone 23 limbs who had recanalised deep venous thrombosis (19) and PVI alone(4). Mean patient follow-up was 35 months. No early deaths or thromboembolism occurred. Complications included severe subcutaneous emphysema(1), neuralgia (7), 1 year later cellulites (1). Ulcers healed in 124 limbs in two months and 58 limbs in 3 months. ulcer recurrence was seen on 12(%6.6) limbs. Clinical severity and disability scores improved significantly after surgery. Conclusion All venous ulcers healed with SEPS combined or not ablation of superficial venous reflux and remain healed 5 year period and symptom-free except recurrent ulcers during the long-term follow-up. SEPS is an effective and safety treatment modality.
