At first, you may feel the weight of the device in your chest. However, over time, most people become accustomed to the way it feels. The pacemaker generator is very small, about the size of two silver dollars stacked on top of each other, and weighs about an ounce or less, depending on the make and model of the device. If the ICD sends a shock to the heart or "fires," the person will feel this as a jolt or kick in the chest.
