Damage to the Broca's area and the Wernicke's area of the brain (left side) typically causes problems with speech and language. Damage to the right side of the brain may interfere with the ability to express emotions or interpret what one sees. Damage on either side can cause paralysis of the opposite side of the body.

With broad complex tachycardia, the ECG will likely show a right bundle branch block or left bundle branch block patterns. Patients who have had their hearts repaired may experience sudden cardiac death. Risk factors for abnormal heart rhythms include: Age (at repair) [9] Male gender [9] Transient complete heart block beyond post operative day ...
Hypoxia differs from hypoxemia and anoxemia, in that hypoxia refers to a state in which oxygen present in a tissue or the whole body is insufficient, whereas hypoxemia and anoxemia refer specifically to states that have low or no oxygen in the blood. [3] Hypoxia in which there is complete absence of oxygen supply is referred to as anoxia.
Agonal respiration occurs in 40% of cardiac arrests experienced outside a hospital environment. Patients with cardiac arrests due to problems with the heart were more likely to experience agonal respirations compared to cardiac arrests from a different cause.
Within a few minutes of anoxia onset in the turtle's brain there is decreased cerebral blood flow that eventually ceases. Meanwhile, glycolysis is stimulated to maintain a near optimum ATP production. [3] This compensatory stimulation of glycolysis occurs because, in the turtle's brain, cytochrome a and a 3 have a low affinity for oxygen. [13]
In general, a shunt may be within the heart or lungs, and cannot be corrected by administering oxygen alone. Shunting may occur in normal states: Anatomic shunting, occurring via the bronchial circulation, which provides blood to the tissues of the lung. Shunting also occurs by the smallest cardiac veins, which empty directly into the left ...
In addition to a heart attack, here are some more heart-related issues for chest pain on the left side. As Dr. Bairey Merz says, these are not conditions you can self-diagnose. Call 911 at once to ...
The left side of the heart is more muscular than the right side of the heart. It pumps oxygenated blood from the lungs into the aorta to perfuse the rest of the body. [4] When the heart has to pump against increased resistance, or afterload, as in the case of a ventricular obstruction, it compensates by growing in size. This adaptation is ...
