Percussive pacing, also known as transthoracic mechanical pacing, is the use of the closed fist, usually on the left lower edge of the sternum over the right ventricle in the vena cava, striking from a distance of 20 – 30 cm to induce a ventricular beat (the British Journal of Anaesthesia suggests this must be done to raise the ventricular pressure to 10–15 mmHg to induce electrical activity).
Since pacemaker correction of the third-degree block requires full-time pacing of the ventricles, a potential side effect is pacemaker syndrome, and may necessitate the use of a biventricular pacemaker, which has an additional 3rd lead placed in a vein in the left ventricle, providing more coordinated pacing of both ventricles.

The KWL chart or table was developed within this methodology and is a form of instructional reading strategy that is used to guide students taking them through the idea and the text. [1] A KWL table is typically divided into three columns titled Know, Want and Learned. The table comes in various forms as some have modified it to include or ...
Crosstalk can only occur in a dual chamber or biventricular pacemaker. It happens less often in more recent models of dual chamber pacemakers due to the addition of a ventricular blanking period, which coincides with the atrial stimulus. This helps to prevent ventricular channel oversensing of atrial output.
Pacing can be done using natural methods without therapeutic intervention and protocols or in more clinical and therapeutic settings including wearing trackers such as Apple Watches, Fitbits, MakeVisible, and other health trackers that have heart rate parameter tracking. Heart rate tracking can be an effective tool when used in a pacing ...
An artificial cardiac pacemaker (or artificial pacemaker, so as not to be confused with the natural cardiac pacemaker) or just pacemaker is an implanted medical device that generates electrical impulses delivered by electrodes to the chambers of the heart either the upper atria, or lower ventricles to cause the targeted chambers to contract and ...
Educator Jim Trelease however, describes Accelerated Reader, along with Scholastic's Reading Counts!, as "reading incentive software" in an article exploring the pros and cons of the two software packages. [18] Stephen D. Krashen, in a 2003 literature review, also asserts that reading incentives is one of the aspects of Accelerated Reader. He ...
The biological pacemaker is intended as an alternative to the artificial cardiac pacemaker that has been in human use since the late 1950s. Despite their success, several limitations and problems with artificial pacemakers have emerged during the past decades such as electrode fracture or damage to insulation , infection , re-operations for ...
