Pediatric stroke is a stroke that occurs in children or adolescents. Stroke affects an estimated 2.5 to 13 per 100,000 children annually. [1] The signs and symptoms of stroke in children, infants, and newborns are different from those in adults. The causes and risk factors of stroke in children are also different from those in adults. [2]
This sinus rhythm is important because it ensures that the heart's atria reliably contract before the ventricles, ensuring as optimal stroke volume and cardiac output. [ 4 ] In junctional rhythm, however, the sinoatrial node does not control the heart's rhythm – this can happen in the case of a block in conduction somewhere along the pathway ...
The hexaxial reference system is a diagram that is used to determine the heart's electrical axis in the frontal plane.. In electrocardiography, left axis deviation (LAD) is a condition wherein the mean electrical axis of ventricular contraction of the heart lies in a frontal plane direction between −30° and −90°.
About 80% of sudden cardiac death is the result of ventricular arrhythmias. [12] Arrhythmias may occur at any age but are more common among older people. [4] Arrhythmias may also occur in children; however, the normal range for the heart rate varies with age. [3]
A mnemonic can be used for some causes of ST depression, namely DEPRESSED ST: [citation needed]. D - Drooping valve (mitral valve prolapse) E - Enlargement of the left ventricle P - Potassium loss R - Reciprocal ST depression (e.g. inferior wall MI) E - Encephalon hemorrhage S - Subendocardial infarct S - Subendocardial ischemia E - Embolism (pulmonary) D - Dilated cardiomyopathy S - Shock T ...
Abnormal: One arm does not move, or one arm drifts down compared with the other side Speech: Have the person say, "You can't teach an old dog new tricks," or some other simple, familiar saying. If the person slurs the words, gets some words wrong, or is unable to speak, that could be a sign of a stroke.
It is an abnormal interictal pattern, consisting of high amplitude and irregular waves and spikes in a background of chaotic and disorganized activity seen on electroencephalogram (EEG), and frequently encountered in infants diagnosed with infantile spasms, although it can be found in other conditions such as tuberous sclerosis.
Abnormal growing central venous pressure indicates either hypotension or hypovolemia. Tachycardia accompanied by declined urine outflow implies either tension pneumothorax , cardiac tamponade or cardiac failure which is thought secondary to cardiac contusion or ischaemic heart disease . [ 6 ]
