The death of Whitney Houston in some ways represents a medical "perfect storm" -- heart disease and a plethora of drugs that can accelerate or aggravate that condition, cardiovascular specialists told MedPage Today.
There is usually reciprocal ST depression in the electrically opposite leads.
It may be impossible to differentiate these two conditions based on the ECG alone. Spodick in as a downward sloping TP segment with specificity for acute pericarditis. BER is a normal variant commonly seen in young, healthy patients. The ST changes may be more prominent at slower heart rates and disappear in the presence of tachycardia.
Note the ST elevation in leads with deep S waves — most apparent in V Deep S waves with ST elevation in V ST depression and T-wave inversion in the lateral leads V Note in this this case there is also right axis deviationwhich is unusual for LVH and may be due to associated left posterior fascicular block.
It is associated with extensive myocardial damage and paradoxical movement of the left ventricular wall during systole. This pattern suggests the presence of a left ventricular aneurysm due to a prior anteroseptal MI. Brugada Syndrome Brugada Syndrome is an inherited channelopathy a disease of myocardial sodium channels that leads to paroxysmal ventricular arrhythmias and sudden cardiac death in young patients.
There is appropriate discordance, with the ST segment and T wave directed opposite to the main vector of the QRS complex.
Widespread ST elevation with concave pericarditis-like morphology in a patient with severe traumatic brain injury.The study went on to hypothesise that, because endothelin-1 increases the calcium sensitivity of arteries, it may sensitise the vasculature to other vasoconstrictor stimuli and prolong coronary vasoconstriction or vasospasm, causing acute myocardial infarction even in people without coronary stenosis.
The Institute for Clinical and Economic Review is an independent non-profit research institute that produces reports analyzing the evidence on the effectiveness and value of drugs and other medical services.
ICER’s reports, developed in partnership with research groups at academic institutions, include evidence-based calculations of prices. Coronary spasm as the cause of myocardial ischaemia in a patient with anomalous origin of the left anterior descending artery from the proximal right coronary artery Left anterior oblique view of the left anterior descending artery from right coronary artery.
There has been several case reports in which coronary vasospasm was documented. Cardiac nurses work in many different environments, including coronary care units (CCU), cardiac catheterization, intensive care units (ICU), operating theatres, cardiac rehabilitation centres, clinical research, cardiac surgery wards, cardiovascular intensive care units .
Spontaneous coronary artery dissection (SCAD) is an important cause of acute coronary syndrome and sudden death in young persons, particularly women.
Associated conditions include fibromuscular dysplasia, peripartum status, and episodes of extreme emotion or exercise. Because of heightened awareness and improved diagnostic accuracy, it is increasingly important for clinicians to understand .
Although the first case report of PDS in noted APO with preserved LV function, most subsequent reports describe severe impairment of left, right or bi- ventricular function, which may be segmental or global (Tables 1 and 2).
